    ALLSTATE PROPERTY & CASUALTY INSURANCE COMPANY ET AL. v.
    SEVIER COUNTY ELECTRIC SYSTEM ET AL.
    Appeal from the Circuit Court for Sevier County
    Nos. 17-CV-795-I, 17-CV-796-IV, 17-CV-798-II, 17-CV-807-IV
    Carter S. Moore, Judge

    No. E2021-01085-COA-R3-CV
    ___________________________________
    This appeal involves several consolidated actions that were filed by insurance companies
    concerning a wildfire that occurred in Sevier County on November 28, 2016. The
    insurance companies alleged that the fire was sparked by a decaying Northern Red Oak
    tree that fell on an electrical service conductor and that the fire quickly spread to
    neighboring properties, including properties owned by their insureds. The insurance
    companies urged that the vegetation management contractor should be held liable for the
    losses for failing to prune or remove the diseased tree before it fell on the conductor. The
    trial court granted summary judgment in favor of the vegetation management contractor,
    determining, inter alia, that the contractor owed no duty to prune trees located near
    service drops or to inspect or remove trees that were outside the right of way that the
    contractor had agreed to maintain. The insurance companies have appealed. Discerning
    no reversible error, we affirm the trial court’s grant of summary judgment to the
    vegetation management contractor.

    OPINION
    I. Factual and Procedural Background
    The plaintiffs in this action consist of various insurance companies, including:
    Allstate Property & Casualty Insurance Company; Allstate Fire & Casualty Insurance
    Company; Allstate Insurance Company; Allstate County Mutual Insurance Company;
    Cincinnati Specialty Underwriters Insurance Group; Cincinnati Insurance Company; LM
    Insurance Corporation; Lexington Insurance Company; Liberty Mutual Fire Insurance
    Company; General Insurance Company of America; Safeco Insurance Company of
    America; State Farm Fire & Casualty Company; State Farm Mutual Automobile
    Insurance Company; United Services Automobile Association; USAA Casualty
    Insurance Company; USAA General Indemnity Company; Garrison Property and
    Casualty Company; Farmers Insurance Exchange; Foremost Insurance Company Grand
    Rapids, Michigan; and United National Insurance Company (collectively, “Plaintiffs”).
    Plaintiffs filed four separate complaints in the Sevier County Circuit Court (“trial court”)
    on November 22, 2017, against the City of Sevierville (“the City”); Sevier County
    Electric System (“SCES”); and SCES’s vegetation management (“VM”) contractor, Wolf
    Tree, Inc. (“Wolf”) (collectively, “Defendants”).
    Plaintiffs alleged that a wildfire broke out on November 28, 2016, near Red Fox
    Trail in Gatlinburg, Tennessee, and quickly spread to adjacent properties, including
    properties owned by Plaintiffs’ insureds, causing damage thereto and resulting in
    insurance claims being filed concerning such damage. Plaintiffs alleged that they had
    paid or would pay these claims, resulting in Plaintiffs having a right of subrogation such
    that they stood in the shoes of their policyholders and could seek payment from
    Defendants.
    1
    We have adopted the list of plaintiffs/appellants provided in the appellants’ brief on page 10, footnote 2,
    having determined such a list difficult to discern from the appellate record.
    -2-
    Plaintiffs urged that although Defendants had notice of a dangerous and defective
    condition concerning a diseased or decaying Northern Red Oak tree located near an
    energized service drop conductor, Defendants failed to take action to prevent harm.
    Plaintiffs claimed that the tree in question had visible signs of rot and decay and that
    Defendants should have known that contact between this tree and the service conductor
    would result in electrical failure, fire, and property damage. According to Plaintiffs, on
    November 28, 2016, this tree fell due to its diseased condition and contacted the service
    conductor, causing electrical arcing and sparks that ignited nearby vegetation and resulted
    in a wildfire (“Cobbly Nob Fire”).
    Plaintiffs alleged that Defendants were negligent due to, inter alia, their failure to
    remove the diseased tree, which created a foreseeable risk to the insureds’ property.
    Moreover, Plaintiffs asserted that because Defendants’ actions or inaction caused the
    Cobbly Nob Fire, Defendants should be held liable for trespass inasmuch as the Cobbly
    Nob Fire constituted an unauthorized entry upon the insureds’ property. Plaintiffs further
    alleged that Defendants’ actions/inaction had created a nuisance that interfered with the
    insureds’ use and enjoyment of their property. With regard to Wolf specifically,
    Plaintiffs advanced that Wolf had a duty to conduct its vegetation management and
    hazardous tree abatement activities in a reasonable, competent, and workmanlike manner
    to prevent trees from contacting the service conductors and ultimately causing damage to
    their insureds’ property. Plaintiffs therefore sought compensatory, consequential, and
    incidental damages as well as pre- and post-interest and attorney’s fees from Defendants.
    Defendants filed motions seeking to consolidate the actions, which motions were
    granted by the trial court. However, Plaintiffs subsequently filed a response suggesting
    that the trial court consolidate the actions involving the Cobbly Nob Fire separately from
    certain related actions filed in the trial court involving another fire that began around
    Little Cove Road in Sevierville, Tennessee (“Little Cove Fire”).2
    SCES and the City filed answers to the complaints denying liability and asserting
    various affirmative defenses, including governmental immunity. Wolf likewise filed
    answers to the complaints denying liability and asserting various affirmative defenses,
    including lack of duty and lack of proximate cause.
    On March 19, 2018, the trial court entered an order setting aside the earlier
    consolidation orders and consolidating all of the cases for purposes of discovery and
    pretrial motions only. The order provided in part that Judge James L. Gass would preside
    over pretrial motions and discovery issues in the consolidated actions and that any party
    could move for consolidation for trial purposes at a later date.
    2
    According to the record, the Little Cove Fire involved trees located on SCES’s “Wears Valley circuit”
    and the Cobbly Nob Fire involved trees located on SCES’s “Jones Cove circuit.”
    -3-
    On April 2, 2018, the City filed a motion for summary judgment, arguing that the
    City was entitled to judgment as a matter of law based on the immunity provisions of the
    Governmental Tort Liability Act (“GTLA”). In support, the City filed the affidavit of
    Allen Robbins, superintendent of SCES. Mr. Robbins explained that the City did not
    own, control, or maintain any of the electric distribution lines. Rather, those lines were
    owned and controlled by SCES. Mr. Robbins further explained that SCES had contracted
    with Wolf to perform VM services and that the City did not perform such services and
    was not a party to the contract. The City filed a similar affidavit executed by Russell
    Treadway, City Manager for the City. The City also filed a statement of undisputed
    material facts. On May 18, 2018, Plaintiffs filed a notice of voluntary dismissal with
    regard to their claims against the City. An order of dismissal concerning Plaintiffs’
    claims against the City was entered on June 1, 2018. On March 7, 2019, SCES filed a
    motion seeking to amend its answer pursuant to Tennessee Rule of Civil Procedure 15 by
    including additional defenses.
    On April 22, 2019, Wolf filed a motion for summary judgment, arguing that Wolf
    was entitled to judgment as a matter of law concerning Plaintiffs’ allegations of
    negligence because Wolf owed no duty to Plaintiffs inasmuch as its contract with SCES
    “explicitly stated that it was not to prune service drops.” Wolf also asserted that it had no
    statutory or common law duty. Wolf further argued that Plaintiffs could show no
    evidence of a negligent or intentional trespass or nuisance. In support, Wolf filed a
    statement of undisputed material facts along with an affidavit from one of Wolf’s
    attorneys, attaching a copy of the contract between Wolf and SCES, a copy of SCES’s
    “Right-of-Way Vegetation Management Requirements & Standards,” portions of the
    National Electrical Safety Code, portions of certain fire and other codes, and various
    photographs. Wolf also attached the affidavit of Ryan Lynch, land surveyor and co-
    owner of Lynch Surveys, LLC, who stated that he had located the tree in question and
    that it was located approximately nineteen feet outside the right of way maintained by
    Wolf.
    On April 26, 2019, the trial court entered an order allowing SCES to amend its
    answer to include additional defenses. On May 3, 2019, the trial court entered an order
    clarifying that dispositive motions would be heard by the judge assigned to the particular
    case in which the motion was filed.
    Wolf and SCES (now collectively, “Defendants”) subsequently filed a joint
    motion asking the trial court to reconsider its May 3, 2019 order such that dispositive
    motions could be filed in the consolidated action and heard by one judge, for reasons of
    judicial economy. Defendants insisted that unless the motions were consolidated, they
    would have to set nine summary judgment hearings before four different judges. Wolf
    asserted that its summary judgment motions, whether filed concerning the Cobbly Nob
    Fire or the Little Cove Fire, contained the same legal arguments. On May 30, 2019, the
    trial court entered an order consolidating the claims concerning the Cobbly Nob Fire into
    -4-
    one action, to be heard by Judge Carter S. Moore, and consolidating the claims
    concerning the Little Cove Fire into a separate action, to be heard by Judge Rex Henry
    Ogle.
    Meanwhile, on May 24, 2019, certain plaintiffs filed a motion seeking to continue
    the hearing respecting Wolf’s summary judgment motion in order to conduct additional
    discovery. On June 21, 2019, the trial court entered an order allowing Plaintiffs to
    conduct discovery limited to the issues “raised in Wolf Tree’s Motions for Summary
    Judgment and necessary to respond to those Motions.” On October 9, 2019, Plaintiffs
    filed a motion seeking to conduct additional depositions, to which they claimed that
    Defendants had refused to agree. On November 15, 2019, the trial court entered an
    agreed order concerning Plaintiffs’ motion, specifying the witnesses that could be
    deposed by Plaintiffs and setting Wolf’s summary judgment motion for hearing.
    On February 10, 2020, Plaintiffs filed a response to Wolf’s motion for summary
    judgment, arguing that Wolf maintained a duty to remove or prune trees with the
    potential to affect electrical lines. Plaintiffs also asserted that they had stated valid claims
    of trespass by fire and nuisance. Plaintiffs filed a response to Wolf’s statement of
    undisputed material facts, identifying certain facts that were in dispute. Plaintiffs also
    filed affidavits and other documents in support of their position. Wolf then filed
    additional documents in support of its motion for summary judgment.
    The trial court conducted a hearing concerning Wolf’s summary judgment motion
    on February 18, 2020. On June 1, 2021, the trial court entered an order granting
    summary judgment in favor of Wolf. With regard to Plaintiffs’ negligence claims, the
    trial court ultimately determined that Wolf did not owe a duty in this matter. Respecting
    any duty based on contract, the trial court found that the clear language of the contract
    provided that Wolf was not to “prune service drops” and that any trees located outside the
    right of way would only be removed at the direction of SCES. The court relied on
    documents demonstrating that the tree in question was located outside the right of way
    and deposition testimony from several witnesses who stated that such trees would only be
    removed if SCES specifically directed the removal. With regard to a statutory duty, the
    court determined that although Tennessee had adopted the National Electric Safety Code
    (“NESC”) by reference in Tennessee Code Annotated § 68-101-104(a)(2), “the language
    of the NESC does not specifically bind contractors.” Finally, with regard to whether
    Tennessee common law imposed any additional duty, the trial court found that it did not.
    Concerning Plaintiffs’ claims of trespass and nuisance, the trial court determined that
    because there was no actionable negligence or intent on Wolf’s part, there could be no
    trespass or nuisance.
    Following the filing of a motion by Wolf, the trial court entered an order of final
    judgment on August 24, 2021, pursuant to Tennessee Rule of Civil Procedure 54.02,
    concerning Plaintiffs’ claims against Wolf. The court determined that there was no just
    -5-
    reason for delay and directed entry of a final judgment dismissing all claims against
    Wolf. The court stayed the claims pending against SCES until this appeal was
    concluded. Plaintiffs timely filed a notice of appeal on September 17, 2021.
    II. Issues Presented
    Plaintiffs present the following issues for this Court’s review, which we have
    restated slightly:
    1.     Whether the trial court erred in its grant of summary judgment in
    favor of Wolf because Wolf owed Plaintiffs a duty to exercise
    reasonable care in the performance of utility tree and vegetation
    management services.
    2.     Whether Tennessee common law’s heightened duty of reasonable
    care for utilities in performing vegetation management surrounding
    power lines applies to contractors hired by utilities to perform
    vegetation management on the utility’s behalf.
    3.     Whether Tennessee’s public policy and the Satterfield factors
    support the imposition of a duty on Wolf under the facts presented in
    this case.
    4.     Whether a vegetation management contractor who agrees to perform
    vegetation management services on behalf of a public utility has a
    duty to comply with state and/or local vegetation management
    regulations applicable to the work and if so, whether Wolf had a
    duty to comply with the NESC, as adopted by Tennessee Code
    Annotated § 68-101-104(a)(2).
    5.     Whether Wolf was required to comply with all state statutes and
    regulations, including the NESC and Tennessee Code Annotated §
    68-101-104(a)(2), based upon its contractual agreement to comply
    with Tree Line USA Guidelines, which included a requirement that
    Tree Line USA members must comply with all state and local rules
    applicable to vegetation management.
    6.     Whether Tennessee recognizes prevailing industry standards, such as
    ANSI A300 and IVM Best Management Practices, as evidence of a
    common law duty owed by utilities and their vegetation management
    contractors performing vegetation management work.
    -6-
    7.     Pursuant to the contract dated December 22, 2014, was Wolf
    required to inspect and/or identify hazardous trees which threatened
    the Sevier County Electric System power lines located along the
    Jones Cove circuit.
    8.     Whether an inspection for hazardous trees, which occurs jointly
    between a utility and a vegetation management contractor or
    independently by the contract, is sufficient to create a duty to do so
    reasonably under Tennessee’s common law assumption of duty
    doctrine.
    9.     Whether the negligent inspection conduct complained of by
    Plaintiffs constitutes either misfeasance or nonfeasance under
    Tennessee law.
    10.    Whether a genuine issue of material fact exists as to Plaintiffs’ claim
    of negligent trespass.
    11.    Whether a genuine issue of material fact exists as to Plaintiffs’ claim
    of nuisance.
    Wolf restates the issues as follows:
    1.     Whether the trial court correctly held that Wolf had no duty to
    inspect, remove, or otherwise make safe trees located outside of a
    contractual right of way, when (1) no statute imposes any such duty,
    (2) the relevant contract imposed no such duty, and (3) Tennessee
    common law imposes no such duty.
    2.     Whether the trial court correctly held that Wolf did not voluntarily
    assume a duty to inspect, remove, or otherwise make safe trees
    located outside of a contractual right of way where the relevant
    evidence and testimony showed that Wolf did not actually undertake
    those acts and the utility did not rely on Wolf to do so.
    3.     Whether the trial court correctly granted summary judgment in favor
    of Wolf concerning Plaintiffs’ trespass claim when that claim
    necessarily relied on Wolf’s alleged negligence, which Plaintiffs
    could not prove.
    4.     Whether the trial court correctly granted summary judgment in favor
    of Wolf concerning Plaintiffs’ nuisance claim when that claim
    -7-
    necessarily relied on Wolf’s alleged negligence, which Plaintiffs
    could not prove.
    III. Standard of Review
    The grant or denial of a motion for summary judgment is a matter of law;
    therefore, our standard of review is de novo with no presumption of correctness. See Rye
    v. Women’s Care Ctr. of Memphis, MPLLC, 
    477 S.W.3d 235
    , 250 (Tenn. 2015); Dick
    Broad. Co. of Tenn. v. Oak Ridge FM, Inc., 
    395 S.W.3d 653
    , 671 (Tenn. 2013) (citing
    Kinsler v. Berkline, LLC, 
    320 S.W.3d 796
    , 799 (Tenn. 2010)). As such, this Court must
    “make a fresh determination of whether the requirements of Rule 56 of the Tennessee
    Rules of Civil Procedure have been satisfied.” Rye, 477 S.W.3d at 250. “Statutory
    construction is a question of law that is reviewable on a de novo basis without any
    presumption of correctness.” In re Estate of Tanner, 
    295 S.W.3d 610
    , 613 (Tenn. 2009).
    As our Supreme Court has explained respecting the requirements for a movant to
    prevail on a motion for summary judgment pursuant to Tennessee Rule of Civil
    Procedure 56:
    [W]hen the moving party does not bear the burden of proof at trial, the
    moving party may satisfy its burden of production either (1) by
    affirmatively negating an essential element of the nonmoving party’s claim
    or (2) by demonstrating that the nonmoving party’s evidence at the
    summary judgment stage is insufficient to establish the nonmoving party’s
    claim or defense. We reiterate that a moving party seeking summary
    judgment by attacking the nonmoving party’s evidence must do more than
    make a conclusory assertion that summary judgment is appropriate on this
    basis. Rather, Tennessee Rule 56.03 requires the moving party to support
    its motion with “a separate concise statement of material facts as to which
    the moving party contends there is no genuine issue for trial.” Tenn. R.
    Civ. P. 56.03. “Each fact is to be set forth in a separate, numbered
    paragraph and supported by a specific citation to the record.” 
    Id.
     When
    such a motion is made, any party opposing summary judgment must file a
    response to each fact set forth by the movant in the manner provided in
    Tennessee Rule 56.03. “[W]hen a motion for summary judgment is made
    [and] . . . supported as provided in [Tennessee Rule 56],” to survive
    summary judgment, the nonmoving party “may not rest upon the mere
    allegations or denials of [its] pleading,” but must respond, and by affidavits
    or one of the other means provided in Tennessee Rule 56, “set forth specific
    facts” at the summary judgment stage “showing that there is a genuine issue
    for trial.” Tenn. R. Civ. P. 56.06. The nonmoving party “must do more
    than simply show that there is some metaphysical doubt as to the material
    facts.” Matsushita Elec. Indus. Co., 475 U.S. [574,] 586, 
    106 S. Ct. 1348
    ,
    -8-
    [
    89 L.Ed.2d 538
     (1986)]. The nonmoving party must demonstrate the
    existence of specific facts in the record which could lead a rational trier of
    fact to find in favor of the nonmoving party. If a summary judgment
    motion is filed before adequate time for discovery has been provided, the
    nonmoving party may seek a continuance to engage in additional discovery
    as provided in Tennessee Rule 56.07. However, after adequate time for
    discovery has been provided, summary judgment should be granted if the
    nonmoving party’s evidence at the summary judgment stage is insufficient
    to establish the existence of a genuine issue of material fact for trial. Tenn.
    R. Civ. P. 56.04, 56.06. The focus is on the evidence the nonmoving party
    comes forward with at the summary judgment stage, not on hypothetical
    evidence that theoretically could be adduced, despite the passage of
    discovery deadlines, at a future trial.
    Rye, 477 S.W.3d at 264-65. “Whether the nonmoving party is a plaintiff or a
    defendant—and whether or not the nonmoving party bears the burden of proof at trial on
    the challenged claim or defense—at the summary judgment stage, ‘[t]he nonmoving party
    must demonstrate the existence of specific facts in the record which could lead a rational
    trier of fact to find in favor of the nonmoving party.’” TWB Architects, Inc. v. The
    Braxton, LLC, 
    578 S.W.3d 879
    , 889 (Tenn. 2019) (quoting Rye, 477 S.W.3d at 265).
    Pursuant to Tennessee Rule of Civil Procedure 56.04, the trial court must “state the legal
    grounds upon which the court denies or grants the motion” for summary judgment, and
    our Supreme Court has instructed that the trial court must state these grounds “before it
    invites or requests the prevailing party to draft a proposed order.” See Smith v. UHS of
    Lakeside, Inc., 
    439 S.W.3d 303
    , 316 (Tenn. 2014).
    IV. Propriety of Grant of Summary Judgment in favor of Wolf
    Concerning Claims of Negligence
    The overarching issue presented by Plaintiffs questions whether the trial court
    properly granted summary judgment in Wolf’s favor with respect to Plaintiffs’ assertion
    that Wolf was negligent. In answer to this query, the trial court determined that Wolf
    could not be held liable for negligence because Wolf owed no duty to inspect or remove
    the tree at issue. Regarding a claim of negligence generally, our Supreme Court has
    elucidated that such a claim requires proof of the following elements:
    (1) a duty of care owed by the defendant to the plaintiff; (2) conduct by the
    defendant falling below the standard of care amounting to a breach of that
    duty; (3) an injury or loss; (4) cause in fact; and (5) proximate or legal
    cause.
    West v. E. Tenn. Pioneer Oil Co., 
    172 S.W.3d 545
    , 550 (Tenn. 2005). The High Court
    went on to explain:
    -9-
    [T]he concept of duty has become an essential element in all negligence
    claims. The duty owed to the plaintiffs by the defendant is in all cases that
    of reasonable care under all of the circumstances. Whether the defendant
    owed the plaintiffs a duty of care is a question of law to be determined by
    the court.
    
    Id.
     (internal citations omitted).
    Plaintiffs argue that a duty existed by virtue of Wolf’s contract with SCES,
    common law, public policy, statute, and/or various regulations. We will address each of
    Plaintiffs’ arguments in turn.3
    A. Wolf’s Contractual Duties
    Plaintiffs postulate that Wolf owed a duty to inspect for, prune, and/or remove
    trees that posed a hazard to electrical lines and conductors by reason of its contract with
    SCES. Our review necessarily focuses on the relevant contractual language. Wolf’s
    contract with SCES (“the Contract”), dated December 22, 2014, provided in pertinent
    part:
    This contract is for tree trimming and other vegetation management for the
    SCES distribution circuit WV 103-224 containing approximately 43.11
    miles of distribution power line. SCES agrees to contract [Wolf] . . . to
    perform tree and other vegetation trimming within proximity of SCES
    power lines and other equipment per provided specifications, requirements
    and mandates. SCES also agrees to contract [Wolf] for other utility
    forestry services as deemed necessary by SCES as specified in submitted
    contractor bid (UNIT PRICING BIDSHEET; TIME AND MATERIALS
    BIDSHEET) of said circuit.
    ***
    [Wolf] shall faithfully uphold and observe all of the qualifications,
    requirements, stipulations and mandates contained within Sevier County
    3
    Although Plaintiffs attempt to argue in their reply brief that questions of fact exist concerning whether
    Wolf acted reasonably, we cannot consider such arguments inasmuch as the arguments were advanced for
    the first time in a reply brief. See Denver Area Meat Cutters & Emprs. Pension Plan v. Clayton, 
    209 S.W.3d 584
    , 594 (Tenn. Ct. App. 2006) (“An appellant cannot abandon an argument advanced in his brief
    and advance a new argument to support an issue in the reply brief.”); see generally Shaw v. Gross, No.
    W2017-00441-COA-R3-CV, 
    2018 WL 801536
    , at *4, n.5 (Tenn. Ct. App. Feb. 9, 2018).

    ***
    [Wolf] hereby assumes entire responsibility and liability in and for any and
    all damages or injury of any kind or nature whatsoever to all persons,
    whether its employees or otherwise, and to all property, growing out of or
    resulting from the execution of the work provided for in this Contract or
    occurring in connection therewith. [Wolf] agrees to defend, indemnify and
    save harmless SCES and/or the City of Sevierville . . . from and against any
    and all losses and expenses, including court costs and attorney’s fees,
    damages or injury growing out of or resulting from or occurring in
    connection with the execution of the work herein provided for; provided,
    however, that [Wolf] will not be held liable for loss of life or injury or
    damage to person or property due to the sole negligence of SCES, its
    agents, officers, servants or employees. This provision shall survive the
    termination or expiration of this Contract.
    The document referenced in the Contract, “Sevier County Electric System Right-
    of-Way Vegetation Management Requirements & Standards” (“SCES Manual”),
    provides in relevant part:
    1.1   Objectives
    [SCES’s] Vegetation Management (VM) program actively manages
    vegetation contained within rights-of-way that may come in contact with
    high voltage power lines and/or other infrastructure equipment to:
    A.     Ensure safety to people, pets and property;
    B.     Ensure reliable electricity to customers;
    C.     Maintain accessible power line rights-of-way;
    D.     Provide and/or enhance habitat for desirable vegetation and
    wildlife species.
    1.2   Purpose
    The purpose of these specifications is to provide direction for the proper
    pruning and management of trees, shrubs, vines and other vegetation which
    are in contact with, or have the potential to come in contact with power
    lines as located within rights-of-way, easements or pruning zones. All
    pruning of trees, shrubs, vines and other vegetation shall be in accordance
    with Tree Line USA requirements as described in:

    2.2   Clearance Minimums: Transmission Lines, Distribution Lines,
    Secondaries, Street Lights and Service Drops
    A.   Transmission Lines: All pruning within transmission line
    rights-of-way will require close coordination between
    CONTRACTOR and SCES.                Pruning of trees near
    transmission conductors may require the line to be de-
    energized.        This will be coordinated between
    CONTRACTOR’s           Supervisor    and    SCES       Project
    Representative. Clearance of transmission lines is both
    weather and load dependent and may not be available upon
    request. Clearances should be requested a minimum of forty-
    eight (48) hours in advance of work. All overhanging limbs
    shall be removed. All brush and trees less than seven (7)
    inches in diameter, excluding landscape-quality and
    ornamental trees located in maintained property owner’s
    yards, shall be removed from the right-of-way and all brush
    chipped. All trees seven (7) inches and larger in diameter
    located in the right-of-way shall be removed only at the
    direction of SCES or SCES Project Representative and at the
    bid-submitted unit pricing. All side-pruning of trees shall be
    a minimum of twenty-five (25) feet from the energized
    conductor.      See Section II: Minimum Clearances-
    Transmission Lines (69kV) in Appendix.
    The transmission right-of-way shall be mechanically cleared
    (i.e. mowed) utilizing a bush-hog and/or a fecon to a
    minimum of twenty-five (25) feet from the centerline of the
    line or a total of fifty (50) feet unless otherwise noted on the
    map or drawing; or so directed by SCES or SCES Project
    Representative.
    ***
    - 12 -
    Distribution Lines: All distribution line rights-of-way shall
    be cleared to a minimum of ten (10) feet from all energized
    conductors (including poles). Single-, two- and three-phase
    distribution lines are not permitted through trees. All over-
    hanging limbs shall be removed. Leaving over-hanging limbs
    will only be considered in certain safe conditions, but in no
    case will a clearance of less than ten (10) feet be allowed. All
    diseased, weak and dead limbs above all conductors shall be
    removed. The final decision regarding leaving over-hanging
    limbs will rest solely with SCES or SCES Project
    Representative. See Section I. Minimum Clearances-Primary
    Power Lines in Appendix.
    ***
    B.    Secondary Conductors: Secondary conductors shall be
    pruned a minimum of ten (10) feet. The definition of a
    “Secondary Conductor” for tree pruning is as follows: open
    three wire or triplex conductors that carry current from the
    secondary side of a distribution transformer to a lift pole or
    poles serving more than one customer. Secondary conductors
    shall be pruned from the connection at the transformer to the
    last lift pole.
    ***
    D.    Service Drops: The definition of “Service Drop” is as
    follows: secondary conductors, which carry current from the
    secondary side of a distribution transformer to a single
    customer connection or from the last lift pole serving more
    than one customer. CONTRACTOR does not prune Service
    drops.
    2.3   Tree Pruning
    The following SCES Vegetation Management practices are in
    accordance with Tree Line USA requirements as described in “Best
    Management Practices-Utility Pruning of Trees” and/or “Pruning
    Trees Near Electric Utility Lines: A Field Guide for Qualified Line-
    Clearance Workers” by Alex Shigo and ANSI A300 tree pruning
    standards. CONTRACTOR shall provide Dr. Shigo’s field guides to
    each crew who performs line clearance pruning. This guide will be
    - 13 -
    available at each work site as a quick reference. Specifically, the
    following practices shall be followed:
    ***
    D.    All dead branches overhanging primary lines at any height
    shall be removed.
    ***
    K.    Special effort shall be made to eliminate all tree parts and
    growth points beneath the power lines, and all weak, diseased
    and dead limbs above the power lines, which may fall or blow
    into them.
    ***
    2.4   Tree, Brush and Vine Removal
    A.    All trees less than seven (7) inches in diameter that will
    require pruning in future years shall be removed from the
    right-of-way, with the exception of low-growing trees (i.e.
    dogwoods, redbuds or ornamental trees) and landscape
    quality trees. . . .
    B.    If CONTRACTOR is instructed by the property owner that he
    wishes to have any trees seven (7) inches and larger in
    diameter removed, CONTRACTOR shall inform SCES or
    SCES Project Representative of the request immediately.
    CONTRACTOR shall not remove trees seven (7) inches and
    larger in diameter until approval is received from SCES or
    SCES Project Representative. . . .
    ***
    D.    All hazardous trees (tall, dead, dying or leaning over primary
    power lines) located outside of the right-of-way and/or
    pruning zone shall be removed at the sole discretion of SCES
    or SCES Project Representative. . . .
    ***
    3.8   Evaluations and Completion
    - 14 -
    A.      SCES or SCES’s Project Representative will evaluate
    CONTRACTOR performance for each circuit at the
    conclusion of the work based on components such as pruning
    techniques, worksite cleanliness, quantity of work, quality of
    work, customer relations, responsiveness to problems and
    their resolution and effectiveness in completing work without
    rework. CONTRACTOR shall be provided with a copy of
    the evaluation report upon written request. CONTRACTOR
    performance evaluations shall be utilized concerning future
    vegetation management CONTRACTOR bids.
    In their complaints, Plaintiffs asserted that the tree at issue made contact with an
    “energized service drop conductor.” As Wolf points out, the Contract expressly provided
    that Wolf was not to prune service drops. However, Wolf concedes that there were high-
    voltage distribution lines that provided power to the service drops. As such, according to
    the Contract, Wolf was to clear the area “to a minimum of ten (10) feet from all energized
    conductors (including poles). . . . All over-hanging limbs shall be removed.”4 Although
    Plaintiffs do not discuss the specific width of the right of way in their brief and some
    dispute exists concerning the exact location of the Northern Red Oak tree that Plaintiffs
    have identified as a potential cause of the Cobbly Nob Fire, the parties agree that the
    trunk of such tree was located several feet outside the applicable right of way as specified
    in the Contract.
    The primary question in this matter is whether Wolf maintained a duty, pursuant to
    the Contract, to inspect, remove, or recommend for removal any trees located outside the
    contractual right of way. In their appellate brief, Plaintiffs rely on the Contract’s
    language stating that all pruning of vegetation by Wolf “shall be in accordance with Tree
    Line USA requirements” as described in:
    A.      “Pruning Trees Near Electrical Utility Lines: A Field Guide for
    Qualified Line-Clearance Workers” by Dr. Alex Shigo;
    B.      “Best Management Practices – Utility Pruning of Trees” by The
    International Society of Arboriculture;
    C.      ANSI A300 guidelines.
    Plaintiffs advance the argument that these “requirements,” specifically the ANSI A300
    guidelines and the “Best Management Practices” published by the International Society
    4
    We note that the trial court stated in its order granting summary judgment that the SCES Manual
    requires “transmission lines rights-of-way to be cleared to a minimum of 25 feet from the centerline of the
    transmission line”; however, the trial court correctly found that the tree at issue was located outside the
    right of way as established by the parties’ experts’ affidavits.
    - 15 -
    of Arboriculture, obligated Wolf to inspect trees outside the right of way that had the
    potential to affect the utility lines. Plaintiffs specifically assert that the above-referenced
    guidelines required Wolf to perform a visual inspection of any trees outside the right of
    way that could possibly fall on or strike the transmission lines in order to check for
    obvious defects and that Wolf should have reported the location of such trees to SCES so
    that SCES could make a decision about their removal. Plaintiffs cite various portions of
    the ANSI A300 guidelines, specifically Parts 7 and 9, as supportive of their arguments.
    By way of example, Plaintiffs particularly cite Part 7, section 75.2, which
    provides:
    Trees and tree branches with the potential to affect utility facilities should
    be monitored for risk, and pruned or removed as appropriate (refer to ANSI
    A300 Part 9 – Tree Risk Assessment). Monitoring intervals, action
    thresholds and methods for mitigation shall be determined by the type of
    facility, regulatory requirements, and available resources.
    ANSI A300, Part 9, concerns tree risk assessment and discusses the various levels of
    assessment that should be performed, how any risks detected should be analyzed, and
    how those risks should be reported. Section 93.6.4.1 clearly states: “It shall be the
    responsibility of the owner, the owner’s agent, or the controlling authority to schedule
    repeat or advanced assessments, determine actions, and implement follow-up
    recommendations, monitoring, and/or mitigation.” However, Plaintiffs contend that Part
    9 generally supports their position that Wolf had a duty to inspect for hazardous trees.5
    The core of the issue presented here is one of contract interpretation. As our
    Supreme Court has instructed:
    We review issues of contractual interpretation de novo. We are guided by
    well-settled principles and general rules of construction. “A cardinal rule
    of contractual interpretation is to ascertain and give effect to the intent of
    the parties.” Allmand [v. Pavletic], 292 S.W.3d [618,] 630 [(Tenn. 2009)]
    (citing Allstate Ins. Co. v. Watson, 
    195 S.W.3d 609
    , 611 (Tenn. 2006)). We
    initially determine the parties’ intent by examining the plain and ordinary
    meaning of the written words that are “contained within the four corners of
    the contract.” 84 Lumber Co. v. Smith, 
    356 S.W.3d 380
    , 383 (Tenn. 2011)
    (citing Kiser v. Wolfe, 
    353 S.W.3d 741
    , 747 (Tenn. 2011)). The literal
    5
    Other portions of the ANSI A300 guidelines simply address proper tree pruning techniques, such as how
    and where tree limbs should be cut in order to “prevent the loss of [utility] service, comply with mandated
    clearance laws, prevent damage to equipment, maintain access, and uphold the intended usage of the
    facility/utility space while adhering to accepted tree care performance standards.” Similarly, Dr. Shigo’s
    “Field Guide” contains detailed drawings and instructions for the proper pruning of trees.
    - 16 -
    meaning of the contract language controls if the language is clear and
    unambiguous. Allmand, 292 S.W.3d at 630. However, if the terms are
    ambiguous in that they are “susceptible to more than one reasonable
    interpretation,” Watson, 
    195 S.W.3d at 611
    , we must apply other
    established rules of construction to aid in determining the contracting
    parties’ intent. The meaning of the contract becomes a question of fact
    only if an ambiguity remains after we have applied the appropriate rules of
    construction.
    Dick Broad., 395 S.W.3d at 659 (other internal citations omitted). Of course, when “an
    executed agreement refers to other documents and makes the conditions of the other
    documents part of the executed agreement, they will be interpreted together as the
    agreement of the parties.” Burns v. Temperature Control Co., 
    371 S.W.2d 804
    , 806
    (Tenn. Ct. App. 1962).
    The instant Contract provided in pertinent part that Wolf was “to perform tree and
    other vegetation trimming within proximity of SCES power lines and other equipment
    per provided specifications, requirements and mandates” and to provide “other utility
    forestry services as deemed necessary by SCES[.]” Attendant thereto, Wolf agreed to
    “faithfully uphold and observe all of the qualifications, requirements, stipulations and
    mandates contained within” the SCES Manual.
    Interpreting the Contract and the SCES Manual together, see Burns, 371 S.W.2d at
    806, and determining the parties’ intent by examining the plain and ordinary meaning of
    the written words utilized therein, see Dick Broad., 395 S.W.3d at 659, it is clear that the
    SCES Manual established the parameters and scope of the tree and vegetation trimming
    and other forestry services that Wolf was to provide. The SCES Manual provided that
    SCES’s vegetation management program was designed to “actively manage[] vegetation
    contained within rights-of-way that may come in contact with high voltage power lines
    and/or other infrastructure equipment” (emphasis added). According to the SCES
    Manual, although Wolf had no duty to prune trees located near service drops, Wolf was
    to clear a minimum of ten feet on either side of the distribution lines and would remove
    all trees within such right of way that were less than seven inches in diameter. The SCES
    Manual further provided that trees seven inches in diameter and larger would be removed
    at the property owner’s request and with SCES approval. Significantly, the SCES
    Manual provided that “hazardous trees,” defined as “tall, dead, dying or leaning over
    primary power lines,” which were located outside the right of way “shall be removed at
    the sole discretion of SCES or SCES Project Representative.”
    Upon our thorough review, we note that neither the Contract nor the SCES Manual
    articulates any requirement that Wolf inspect trees outside the right of way to determine
    whether they are hazardous or should be removed. Indeed, these documents do not
    impose a duty upon Wolf to remove or seek approval to remove such trees, either.
    - 17 -
    Instead, any question concerning removal of trees located outside the right of way, like
    the tree at issue here, is addressed to SCES’s sole discretion.
    We note that Plaintiffs do not exclusively focus on the language contained within
    the four corners of the Contract or the SCES Manual as creating a duty that Wolf would
    inspect trees outside the right of way and recommend their removal; rather, Plaintiffs also
    rely on provisions contained within the additional documents referred to in the SCES
    Manual as “requirements” for proper tree “pruning” and argue that these additional
    documents imposed a duty upon Wolf that the Contract and SCES Manual may not have.
    The provision in the SCES Manual upon which Plaintiffs rely, however, states that its
    purpose is to “provide direction for the proper pruning and management of trees, shrubs,
    vines and other vegetation which are in contact with, or have the potential to come in
    contact with power lines as located within rights-of-way, easements or pruning zones”
    and that “pruning of trees, shrubs, vines and other vegetation shall be in accordance with
    Tree Line USA requirements as described in” the ANSI A300 guidelines and the
    accompanying “Best Management Practices” published by the International Society of
    Arboriculture, as well as Dr. Shigo’s “Field Guide” (emphasis added).
    As our Supreme Court has elucidated:
    We first recognize the foundational principles in all of Tennessee
    contract law. The common thread in all Tennessee contract cases—the
    cardinal rule upon which all other rules hinge—is that courts must interpret
    contracts so as to ascertain and give effect to the intent of the contracting
    parties consistent with legal principles.
    Also foundational to our jurisprudence is the principle that the rules
    used for contract interpretation “have for their sole object ‘to do justice
    between the parties, by enforcing a performance of their agreement
    according to the sense in which they mutually understood it at the time it
    was made.’” McNairy v. Thompson, 
    33 Tenn. 141
    , 149 (1853) (quoting
    Chitty on Con. 73).
    Individual Healthcare Specialists, Inc. v. BlueCross BlueShield of Tenn., Inc., 
    566 S.W.3d 671
    , 688 (Tenn. 2019) (other internal citations omitted). To that end, “the object
    to be attained in construing a contract is to ascertain the meaning and intent of the parties
    as expressed in the language used and to give effect to such intent if it does not conflict
    with any rule of law, good morals, or public policy.” Planters Gin Co. v. Fed. Compress
    & Warehouse Co., Inc., 
    78 S.W.3d 885
    , 890 (Tenn. 2002) (quoting 17 Am.Jur.2d,
    Contracts, § 245).
    - 18 -
    Upon careful review, we determine the language of the Contract and the
    incorporated SCES Manual to be clear and unambiguous.6 Wolf’s contractual duty was
    to clear a minimum of ten feet on either side of the distribution lines and remove all trees
    within such right of way measuring less than seven inches in diameter; Wolf had no duty
    to prune trees located near service drops. Decisions regarding removal of trees seven
    inches in diameter or larger or trees located outside the ten foot right of way were left to
    the sole discretion of SCES. No contractual duty of inspection was imposed upon Wolf
    for trees located outside the ten foot right of way.
    According to the Contract and the SCES Manual, as concerning the proper
    methods for “pruning” of trees and other vegetation, the guidelines presented in the
    additional listed publications were to be followed. However, inasmuch as the Contract
    and SCES Manual placed no duty upon Wolf to inspect trees outside the right of way,
    much less to remove them unless directed to do so by SCES, such a duty could not be
    added by reference to additional guidelines concerning only proper “pruning” methods.
    By referring to these additional guidelines in terms of proper pruning only, SCES clearly
    limited application of those documents to pruning methods rather than to all subjects
    covered therein.
    In short, the plain and ordinary meaning of the clear and unambiguous written
    words “contained within the four corners of the contract,” see 84 Lumber Co. v. Smith,
    
    356 S.W.3d 380
    , 383 (Tenn. 2011), provided that the additional guidelines referenced
    were to be applied to methods of pruning only. These additional documents did not add
    to or vary the terms of the contractual duties to which Wolf had agreed. Therefore,
    because the language of the Contract imposed no duty upon Wolf to inspect for
    hazardous trees located outside the right of way, the trial court properly granted summary
    judgment to Wolf on that basis.
    B. Statutory Duty
    Plaintiffs additionally posit that Wolf has a statutory duty relative to its vegetation
    management work because Tennessee has adopted the NESC as applicable to
    maintenance and operation of Tennessee electrical lines, see 
    Tenn. Code Ann. § 68-101
    -
    104, and the NESC provides that hazardous trees posing a danger to utility facilities
    should be pruned or removed. Tennessee Code Annotated § 68-101-104 (2013), found
    within “Miscellaneous Safety and Environmental Regulations” in Title 68 of the
    Tennessee Code, provides in relevant part:
    6
    Because the Contract and incorporated SCES Manual contain no ambiguity, we need not resort to the
    use of parol evidence for interpretation, as Plaintiffs urge. See, e.g., Allstate Ins. Co. v. Watson, 
    195 S.W.3d 609
    , 612 (Tenn. 2006).
    - 19 -
    (a)    The American National Standard Electrical Safety Code, edition
    dated August 1, 2011, prepared and published by the Institute of
    Electrical and Electronics Engineers, Inc., 345 East 47th Street, New
    York, New York, 10017, is adopted by the general assembly for
    application for all processes within the state of Tennessee as the
    official electrical safety code, to provide a standard for safeguarding
    of persons from hazards arising from the installation, operation, or
    maintenance of:
    (1)    Conductors and equipment in electric-supply stations; and
    (2)    Overhead       and    underground     electric-supply    and
    communication lines, and work rules for the construction,
    maintenance, and operation of electric-supply and
    communication lines and equipment, and the provisions of
    such National Electrical Safety Code are adopted herein by
    reference and shall not be copied in the codified sections or
    provisions of the Tennessee Code.
    In support of their argument that the NESC imposes a statutory duty upon Wolf,
    Plaintiffs rely particularly on Section 218 of the NESC, which states: “Vegetation that
    may damage ungrounded supply conductors should be pruned or removed. Vegetation
    management should be performed as experience has shown to be necessary.”
    Notwithstanding, as Wolf points out, a note to Section 218 provides that “right-of-way
    limitations” should be considered as one of the “[f]actors . . . in determining the extent of
    vegetation management required.” Another such factor is the “vegetation’s location in
    relation to the conductors.” As a second note to Section 218 provides: “It is not practical
    to prevent all tree-conductor contacts on overhead lines.”
    The trial court determined that the above-referenced NESC provision “does not
    specifically bind contractors.” We agree. Our consideration of the NESC provisions
    contained in the appellate record leads to the conclusion that it is designed to serve as a
    “standard (or basis of the standard) of safe practice for public and private utilities in the
    United States,” as stated in its introduction (emphasis added). Accordingly, any duty to
    prune or remove vegetation that could impact electrical supply lines would lie first and
    foremost with SCES. However, as Plaintiffs note, some authority exists supporting the
    position that utilities can delegate certain duties respecting the “maintenance” of utility
    systems to independent contractors. See, e.g., Dempsey v. Correct Mfg. Corp., 
    755 S.W.2d 798
    , 806 (Tenn. Ct. App. 1988) (explaining that “maintenance or alteration of . . .
    objects in proximity to the system which are not directly involved in the carrying of
    electrical energy is a matter which may be committed to independent contractors” while
    also explaining generally that “tree-cutting” is not included in “maintaining” utilities as
    used in the NESC and other regulations). As such, whether or not the NESC was
    - 20 -
    intended to apply to contractors employed by utilities, it appears that utilities can delegate
    certain duties thereunder to independent contractors under appropriate circumstances.
    See 
    id.
    Assuming, arguendo, that SCES could properly delegate its duty, pursuant to the
    NESC, to Wolf for pruning or removal of vegetation that might damage ungrounded
    supply conductors, any question relative to the parameters and scope of the duty
    delegated to Wolf would be controlled by the parties’ Contract. See, e.g., Frazee v. Med
    Ctr. Inns of Am., Inc., No. 01A01-9301-CV-00034, 
    1993 WL 312674
    , at *4 (Tenn. Ct.
    App. Aug. 18, 1993) (explaining that when a party delegates a duty to another, the
    respective duties of each are delineated by their contractual agreement). We reiterate that
    the Contract only required Wolf to remove trees located within the right of way and
    measuring less than seven inches in diameter without SCES’s authorization and/or
    direction. The tree at issue here was undisputedly located outside the right of way.
    Therefore, SCES maintained sole discretion as to its removal. Ergo, Plaintiffs’ assertion
    that Wolf owed a statutory duty to remove the tree at issue pursuant to the NESC must
    fail for similar reasons that were fatal to Plaintiffs’ position that Wolf owed a duty
    pursuant to the parties’ contract. We accordingly conclude that Wolf owed no statutory
    duty to remove the tree at issue based on Tennessee Code Annotated § 68-101-104 or the
    NESC, and we affirm the trial court’s grant of summary judgment as to this issue.7
    C. Assumption of Common Law Duty
    Plaintiffs contend that because Wolf, on occasion, performed visual inspections of
    trees existing both inside and outside the right of way while it performed vegetation
    pruning and removal under the Contract, Wolf voluntarily assumed a duty to perform
    such inspections outside the right of way defined in the Contract to identify hazardous
    trees for pruning or removal. Plaintiffs rely on the common law statement of a general
    principle found in Biscan v. Brown, 
    160 S.W.3d 462
    , 482-83 (Tenn. 2005), that: “One
    who assumes to act, even though gratuitously, may thereby become subject to the duty of
    acting carefully” (quoting Stewart v. State, 
    33 S.W.3d 785
    , 793 (Tenn. 2000)). This
    principle applies in situations where “a party has undertaken to provide services to
    another” and where a third party “suffer[s] physical harm from the negligent performance
    of the undertaking.” See Grogan v. Uggla, 
    535 S.W.3d 864
    , 873 (Tenn. 2017).
    In further defining this principle, Tennessee courts have often cited with approval
    Section 324A of the Restatement (Second) of Torts, which provides:
    7
    Plaintiffs also argue that the affidavit of their vegetation management expert, Michael Neal, opining that
    “[Wolf’s] failure to adequately prune or remove the subject tree suffering from obvious structural defects
    was a violation of the NESC statutory standard of care” was sufficient to establish a statutory duty. We
    note, however, this Court’s previous instruction that “content meaning and application of statutes and
    regulations are not a matter of fact to be proven by the affidavit of an expert witness, but are a matter of
    law.” Dempsey, 
    755 S.W.2d at 806
    .
    - 21 -
    One who undertakes, gratuitously or for consideration, to render services to
    another which he should recognize as necessary for the protection of a third
    person or his things, is subject to liability to the third person for physical
    harm resulting from his failure to exercise reasonable care to protect his
    undertaking, if
    (a)    his failure to exercise reasonable care increases the risk of such
    harm, or
    (b)    he has undertaken to perform a duty owed by the other to the third
    person, or
    (c)    the harm is suffered because of reliance of the other or the third
    person upon the undertaking.
    See Grogan, 535 S.W.3d at 874. The question of whether a party has assumed such a
    duty is a question of law. See id.; see also Biscan, 
    160 S.W.3d at 483
    .
    Plaintiffs contend that Wolf should be deemed to have assumed a common law
    duty to inspect for hazardous trees located beyond the right of way specified in the
    Contract because each of the party witnesses who testified via deposition in this matter
    affirmed that Wolf performed hazardous tree inspections outside the right of way.
    Respectfully, our review of the deposition testimony presented demonstrates that
    Plaintiffs’ argument is unpersuasive. For example, Jeff Hedrick, the corporate
    representative for SCES, testified that trees were “typically” marked for removal by
    SCES inspectors. Mr. Hedrick clarified that although the VM contractor could “point a
    tree out,” the SCES inspector “will have the discretion whether to cut that tree or not.”
    During this questioning, Mr. Hedrick made no distinction concerning whether he was
    referring to trees located inside or outside the right of way.
    Nathan Dunn, a vegetation inspector for SCES who worked on the Jones Cove
    circuit, testified that although Wolf employees at times asked him to look at a particular
    tree or conferred with him about a tree, it was ultimately SCES’s responsibility to
    identify trees for removal. Steven Springer, the supervisor of vegetation management for
    SCES, testified that SCES employees were tasked with identifying hazardous trees and
    had the final say on whether trees seven inches in diameter or larger were removed. Mr.
    Springer added that although VM contractors were not required to notify SCES regarding
    trees that needed to be removed outside the right of way, they did so at times. However,
    Mr. Springer clarified that removal of trees outside the right of way was SCES’s “call.”
    Jared Underwood, a utility forester for SCES assigned to the Wears Valley circuit,
    testified that he was present on that circuit daily while Wolf employees were working.
    - 22 -
    He also testified that he had inspected the circuit before Wolf began work. Mr.
    Underwood expressly stated that it was his responsibility to identify trees for removal and
    that he would “go ahead” of Wolf employees to mark trees that needed to be removed.
    Mr. Underwood also related that although Wolf’s employees sometimes pointed out a
    tree or requested that he look at a tree, the responsibility to identify trees for removal was
    SCES’s. Mr. Underwood made no distinction in this testimony concerning whether he
    was referring to trees located inside or outside the right of way.
    Daniel Allen, a former employee of Wolf who served as a supervisor for the
    Wears Valley and Jones Cove circuits during the relevant time frame, testified that while
    he sometimes pointed out trees to the SCES inspector that he felt needed to be removed
    within the right of way, he would only mention a tree outside the right of way if it was
    “noticeable.” David Jackson, the operations manager for Wolf during the applicable time
    frame, testified that he inspected the circuit before Wolf bid on the job and helped
    calculate the cost of the work for bidding purposes. Notably, Mr. Jackson did not state
    that he had inspected any trees located outside the right of way or that he had marked any
    such trees for potential removal.
    In considering the above-referenced testimony in light of Plaintiffs’ claim of
    voluntary assumption of a common law duty, we find the Supreme Court’s opinion in
    Grogan to be instructive. See 535 S.W.3d at 873-876. In Grogan, the High Court was
    asked to determine whether a residential home inspector, who had performed an
    inspection of a home for a potential home buyer, could subsequently be held liable for the
    injuries of a third party who fell from the home’s deck because the deck railing, which
    was alleged to be improperly built, collapsed. Id. at 866. The injured party filed suit
    against the home inspector and claimed, inter alia, that the inspector had performed a
    negligent home inspection. Id.
    The Grogan Court, in analyzing the negligence issue, considered whether Section
    324A should apply and whether the inspector had undertaken a duty for the protection of
    the injured third party. Id. at 874. In determining whether the inspector had actually
    undertaken such a duty, the Court reviewed the inspector’s contract with the home owner
    for a home inspection, deposition testimony, and the “relevant statutes and regulations.”
    Id. at 874-75. Specifically, the plaintiff had alleged that the inspector failed to find that
    the deck railing was non-compliant relative to the applicable building code, but the home
    inspection contract stated that the inspection was “visual only and not a building code
    inspection,” and the inspector testified that he was not a building codes inspector. Id. at
    875. Furthermore, the contract stated that “[n]ot all conditions may be apparent” and that
    the inspector was not liable for “patent or latent defects in materials, workmanship, or
    other conditions.” Id. Based primarily on limitations stated in the inspection contract
    and the inspector’s testimony, the Court determined that the inspector had not voluntarily
    assumed any duty beyond that which he owed to his client pursuant to their agreement.
    Id. at 876.
    - 23 -
    Similarly, here, the Contract and incorporated SCES Manual expressly provide
    that SCES has sole discretion concerning the removal of trees located outside the right of
    way, and no duty to inspect for hazardous trees outside the right of way is imposed upon
    Wolf. The deposition testimony unequivocally established that trees located outside the
    right of way were only removed with SCES’s express authorization. Moreover, although
    there existed some testimony that Wolf employees occasionally pointed out trees that
    they believed should be removed, the duty to inspect for such trees outside the right of
    way belonged to SCES. Mr. Dunn, who worked daily on the Jones Cove circuit, testified
    that although Wolf employees at times asked him to look at a particular tree or conferred
    with him about a tree, it was ultimately SCES’s responsibility to identify trees for
    removal. Likewise, Mr. Allen, who worked on the Jones Cove circuit on Wolf’s behalf,
    testified that he only mentioned a tree for removal authorization outside the right of way
    if it was “noticeable.” Based on the facts presented concerning Wolf’s agreement with
    SCES and the respective deposition testimony, we conclude that the trial court correctly
    determined that Wolf did not voluntarily assume a common law duty to inspect for
    hazardous trees located outside the right of way.
    D. Imposition of Common Law Duty and Misfeasance/Nonfeasance
    Plaintiffs also rely on a “common law duty” with respect to their negligence claim
    against Wolf. Tennessee common law recognizes that duty consists of a “legal obligation
    to conform to a reasonable person standard of care in order to protect others against
    unreasonable risks of harm.” Satterfield v. Breeding Insulation Co., 
    266 S.W.3d 347
    , 355
    (Tenn. 2008). As our Supreme Court explained:
    As a general rule, persons have a duty to others to refrain from engaging in
    affirmative acts that a reasonable person “should recognize as involving an
    unreasonable risk of causing an invasion of an interest of another” or acts
    “which involve[] an unreasonable risk of harm to another.” Restatement
    (Second) of Torts §§ 284, 302, at 19, 82 (1965). Thus, if an individual
    “acts at all, [he or she] must exercise reasonable care to make his [or her]
    acts safe for others.” Restatement (Second) of Torts § 4 cmt. b, at 8. The
    core of negligence is the violation of this requirement by engaging in
    “behavior which should be recognized as involving unreasonable danger to
    others.” W. Page Keeton, Prosser and Keeton on the Law of Torts § 31, at
    169 (5th ed.1984) [hereinafter “Prosser and Keeton”].
    These rules do not, however, require that persons always act
    reasonably to secure the safety of others. Rather, they serve a more limited
    role as restraints upon a person’s actions that create unreasonable and
    foreseeable risks of harm to others. Expounding upon this point more than
    a century ago, Professor Francis H. Bohlen asserted that “[t]here is no
    - 24 -
    distinction more deeply rooted in the common law and more fundamental
    than that between misfeasance and non-feasance, between active
    misconduct working positive injury to others and passive inaction, a failure
    to take positive steps to benefit others, or to protect them from harm not
    created by any wrongful act of the defendant.”
    Id. at 355-56 (quoting Francis H. Bohlen, The Moral Duty to Aid Others as a Basis of
    Tort Liability, 56 U. PA. L. REV. 217, 219 (1908)).
    The Satterfield Court further elucidated:
    Professor Bohlen is not the only scholar to offer an eloquent and
    enlightening articulation of the distinction between misfeasance and
    nonfeasance. Dean Keeton and Dean Prosser explained the distinction as
    follows:
    In the determination of the existence of a duty, there runs
    through much of the law a distinction between action and
    inaction. . . . [T]here arose very early a difference, still
    deeply rooted in the law of negligence, between
    “misfeasance” and “nonfeasance”—that is to say, between
    active misconduct working positive injury to others and
    passive inaction or a failure to take steps to protect them from
    harm. The reason for the distinction may be said to lie in the
    fact that by ‘misfeasance’ the defendant has created a new
    risk of harm to the plaintiff, while by ‘nonfeasance’ he has at
    least made his situation no worse, and has merely failed to
    benefit him by interfering in his affairs.
    Prosser and Keeton § 56, at 373.
    Id. at 356 (footnote omitted).
    Plaintiffs advance that Wolf’s alleged failure to properly inspect for or remove the
    hazardous tree at issue constitutes misfeasance rather than nonfeasance. Plaintiffs
    predicate their assertion of misfeasance in part on their position that Wolf owed a
    heightened duty of care to the public pursuant to Tennessee common law “commensurate
    with the extreme danger posed by the electrical power lines.”
    In support of their postulate, Plaintiffs rely on this Court’s opinions in Rogers v.
    City of Chattanooga, 
    281 S.W.2d 504
    , 508 (Tenn. Ct. App. 1954) (“[T]he City was
    required not only to install or erect the uninsulated high-tension wires, which carried
    death for anyone who came in contact with them, at a safe height above the ground, but . .
    - 25 -
    . was also under a duty to patrol and inspect said lines at frequent intervals to see that the
    lines did not later become unsafe and dangerous by changing conditions, such as,
    overhanging tree branches, erection of buildings, etc.”); Int’l Harvester Co. v. Sartain,
    
    222 S.W.2d 854
    , 867 (Tenn. Ct. App. 1948) (“One who deals with an article which is
    imminently dangerous owes a public duty to all to whom it may come and who may be
    endangered thereby to exercise caution adequate to the peril involved[.]”); and Rollins v.
    Elec. Power Bd. of Metro. Gov’t of Nashville & Davidson Cnty., No. M2003-00865-
    COA-R3-CV, 
    2004 WL 1268431
    , at *6 (Tenn. Ct. App. June 8, 2004) (“It is the supplier
    of electricity who is charged with the heightened duties for public safety[.]”). The
    obvious distinction between the case at bar and Rogers, Sartain, and Rollins, however, is
    that in those cases, the “heightened” duty being analyzed belonged to the owner or
    operator of the electrical lines, not a private contractor hired to manage vegetation such
    as Wolf. As such, the cases from this Court relied upon by Plaintiffs for imposition of a
    heightened duty are unavailing.
    Plaintiffs also cite a decision from the California Court of Appeals, CHY Co. v.
    Util. Tree Servs., Inc., No. C054697, 
    2008 WL 4838684
    , at *2 (Cal. Ct. App. Nov. 10,
    2008), as authority for the contention that a VM contractor’s improper performance of
    tree inspections constitutes misfeasance rather than nonfeasance. Plaintiffs’ reliance is
    again misplaced for at least two reasons. First, the vegetation management contractor in
    CHY had a contractual duty to inspect for hazardous trees, whereas Wolf did not. See 
    id.
    Second, although “cases from other jurisdictions are sometimes persuasive in this Court,
    they do not operate as controlling authority.” Wofford v. M.J. Edwards & Sons Funeral
    Home Inc., 
    490 S.W.3d 800
    , 817 n.12 (Tenn. Ct. App. 2015). We therefore determine
    CHY to be unavailing as well.
    Plaintiffs also place special emphasis on the factors listed in Satterfield concerning
    utilization of a balancing test for foreseeability and gravity of harm in determining a
    defendant’s duty. We emphasize, however, that in instances where the defendant has
    made the plaintiff’s situation no worse (nonfeasance), there is generally no duty to act.
    See Satterfield, 266 S.W.3d at 356. Exceptions to this rule exist for certain special
    relationships between the parties, none of which are applicable to the parties herein. Id.
    at 359. The Satterfield balancing test and its applicability in situations concerning
    misfeasance versus nonfeasance was succinctly explained by this Court in Koczera v.
    Steele, 
    570 S.W.3d 242
    , 247-49 (Tenn. Ct. App. 2018):
    “As a general rule, persons have a duty to others to refrain from
    engaging in affirmative acts that a reasonable person ‘should recognize as
    involving an unreasonable risk of causing an invasion of an interest of
    another’ or acts ‘which involve[] an unreasonable risk of harm to another.’”
    Satterfield v. Breeding Insulation Co., 
    266 S.W.3d 347
    , 355 (Tenn. 2008)
    (quoting Restatement (Second) of Torts §§ 284, 302, at 19, 82 (1965)).
    - 26 -
    Such affirmative acts are known as “misfeasance.” Giggers [v. Memphis
    Hous. Auth.], 277 S.W.3d [359,] 364 [(Tenn. 2009)].
    Conversely, “nonfeasance” is “passive inaction or a failure to take
    steps to protect [others] from harm.” Satterfield, 266 S.W.3d at 356
    (quoting W. Page Keeton, Prosser and Keeton on the Law of Torts § 56
    (5th ed. 1984)).
    As for nonfeasance, Tennessee’s courts generally have
    declined to impose a duty to act or to rescue. Bradshaw v.
    Daniel, 854 S.W.2d [865,] 870 [(Tenn. 1993)]; Newton v.
    Tinsley, 970 S.W.2d [490,] 492 [(Tenn. Ct. App. 1997)].
    Simply stated, persons do not ordinarily have a duty to act to
    protect others from dangers or risks except for those that they
    themselves have created. Biscan v. Brown, 
    160 S.W.3d 462
    ,
    478-79 (Tenn. 2005); Nichols v. Atnip, 
    844 S.W.2d 655
    , 661
    (Tenn. Ct. App. 1992).
    Tennessee’s general rule with regard to nonfeasance is
    consistent with the Restatement’s position that “[t]he fact . . .
    the actor realizes or should realize that action on his part is
    necessary for another’s aid or protection does not of itself
    impose upon him a duty to take such action.” Restatement
    (Second) of Torts § 314, at 116. This general and long-
    standing principle of tort law [is] often termed either the “no
    duty to act rule” or the “no duty to rescue rule”. . . .
    Id. at 357.
    However, in order to mitigate the harshness of the common law rule,
    our courts have recognized certain exceptions where “the defendant has a
    special relationship with either the individual who is the source of the
    danger or the person who is at risk,” such as between a landlord and tenant.
    Giggers, 277 S.W.3d at 364. Thus, under Tennessee law, “‘while an actor
    is always bound to prevent his acts from creating an unreasonable risk to
    others, he is under the affirmative duty to act to prevent another from
    sustaining harm only when certain socially recognized relations exist which
    constitute the basis for such legal duty.’” Turner v. Jordan, 
    957 S.W.2d 815
    , 818 (Tenn. 1997) (quoting Bradshaw, 854 S.W.2d at 871).
    In her deposition, Ms. Steele stated that a sheriff’s deputy arrived at
    the office where she worked on September 29, 2008, and asked her if she
    was the office manager, to which she responded “yes.” According to Ms.
    - 27 -
    Steele, he handed her “papers for Dr. O’Connor,” but she did not know
    what the papers were “until after [she] had them.” She could not remember
    the officer explaining to her what the papers were, and the two did not
    discuss whether or not she was authorized to accept process on Dr.
    O’Connor’s behalf. After he left, she handed the documents to Dr. Pearson.
    The issue here is one of characterization. Plaintiffs argue that both
    Ms. Steele and Dr. Pearson had a duty to inform the sheriff’s deputy who
    delivered the documents for Dr. O’Connor that they were not authorized to
    accept process on Dr. O’Connor’s behalf—or at least to inquire about the
    nature of the delivered papers. Plaintiffs characterize this as a “duty to
    disclose” or a “duty not to interfere.” Still, the crux of Plaintiffs’ argument
    is that Defendants had a duty to take some action to correct the officer’s
    error in serving process on one not authorized to accept it. There is,
    however, no special relationship recognized at law between Defendants and
    Plaintiffs that qualifies as an exception to the “no duty to act rule.”
    Plaintiffs make much out of the trial court’s “fail[ure] to apply the
    balancing test outlined in Satterfield to determine whether or not
    Defendants[] had a duty.” The Tennessee Supreme Court explained the
    balancing test Plaintiffs refer to as follows:
    When the existence of a particular duty is not a given or when
    the rules of the established precedents are not readily
    applicable, courts will turn to public policy for guidance.
    Doing so necessarily favors imposing a duty of reasonable
    care where a defendant’s conduct poses an unreasonable and
    foreseeable risk of harm to persons or property. When
    conducting this analysis, the courts have considered, among
    other factors: (1) the foreseeable probability of the harm or
    injury occurring; (2) the possible magnitude of the potential
    harm or injury; (3) the importance or social value of the
    activity engaged in by the defendant; (4) the usefulness of the
    conduct to the defendant; (5) the feasibility of alternative
    conduct that is safer; (6) the relative costs and burdens
    associated with that safer conduct; (7) the relative usefulness
    of the safer conduct; and (8) the relative safety of alternative
    conduct.
    Satterfield, 266 S.W.3d at 365 (citations and internal quotation marks
    omitted). However, Plaintiffs erroneously characterize the alleged
    negligence of Ms. Steele and Dr. Pearson as misfeasance rather than
    nonfeasance. The balancing test above has generally been applied where a
    - 28 -
    defendant’s conduct poses an unreasonable and foreseeable risk of harm,
    not a defendant’s inaction. See Grogan v. Uggla, 
    535 S.W.3d 864
    , 871-72
    (Tenn. 2017) (declining to analyze the issue of duty under the “Satterfield
    duty factors” where a defendant inspect[or] failed to identify a source of
    harm during an inspection); see also, e.g., Burroughs v. Magee, 
    118 S.W.3d 323
    , 329-35 (Tenn. 2003); Satterfield, 266 S.W.3d at 365-69.
    See also Satterfield, 266 S.W.3d at 355 (explaining that rules with respect to
    “unreasonable risk” serve as “restraints upon a person’s actions that create” such risk).
    Similarly, here, Plaintiffs erroneously characterize Wolf’s alleged failure to
    inspect or remove hazardous trees as misfeasance; however, what Plaintiffs have alleged
    is not “active misconduct working positive injury to others,” but rather “passive inaction”
    on Wolf’s part or Wolf’s “failure to take steps to protect” Plaintiffs’ insureds from harm.
    See Satterfield, 266 S.W.3d at 356. In essence, Plaintiffs have alleged nonfeasance, and
    Wolf therefore maintained no common law duty to act. See id.
    Plaintiffs also argue that the ANSI A300 standards represented an “industry
    custom or practice” imposing a duty upon Wolf to inspect for hazardous trees that could
    impact the electrical lines. Plaintiffs urge that various witnesses testified via deposition
    that compliance with these standards was mandated by the Contract. We reiterate that
    although the ANSI A300 and other such standards were clearly applicable to pruning
    methods pursuant to the language of the Contract, this fact does not warrant imposition of
    an additional duty upon Wolf (to inspect for hazardous trees outside the right of way) for
    which Wolf did not bargain in the Contract. Likewise, the fact that Plaintiffs’ expert, Mr.
    Neal, opined that the ANSI standards or other regulations would apply to Wolf’s work as
    a VM contractor does not necessarily mean that Wolf could be charged with a duty to
    inspect trees located outside the right of way that Wolf had contractually agreed to
    maintain. We again note that “content meaning and application of . . . regulations are not
    a matter of fact to be proven by the affidavit of an expert witness, but are a matter of
    law.” Dempsey, 
    755 S.W.2d at 806
    .
    We accordingly conclude that Wolf owed no duty to Plaintiffs or their insureds in
    this matter by virtue of Wolf’s contract with SCES, Tennessee common law, public
    policy, statute, or applicable regulations. We therefore affirm the trial court’s grant of
    summary judgment in Wolf’s favor based on a lack of duty.
    V. Remaining Claims
    Plaintiffs assert that the trial court improperly granted summary judgment as to
    their remaining claims of negligent trespass and nuisance. As to their claim of negligent
    trespass by fire, such claim is premised upon their allegation that Wolf negligently caused
    - 29 -
    the property of Plaintiffs’ insureds to be invaded by fire. In their brief, Plaintiffs cite
    Section 165 of the Restatement (Second) of Torts, which states:
    One who recklessly or negligently, or as a result of an abnormally
    dangerous activity, enters land in the possession of another or causes a
    thing or third person so to enter is subject to liability to the possessor if, but
    only if, his presence or the presence of the thing or the third person upon
    the land causes harm to the land, to the possessor, or to a thing or a third
    person in whose security the possessor has a legally protected interest.
    (Emphasis added.)
    As the trial court properly reasoned, Plaintiffs have failed to demonstrate
    negligence on Wolf’s part due to lack of duty. Plaintiffs have likewise failed to prove
    that Wolf acted recklessly or engaged in an abnormally dangerous activity. As such,
    Plaintiffs cannot rely on the above Restatement section as a basis for imposing liability
    on Wolf.
    With respect to their remaining claim of nuisance, Plaintiffs argue that their claim
    of nuisance is not dependent upon a finding of negligence, asserting that “nuisance may
    exist either with or without negligence.” Roles-Walter v. Kidd, No. M2017-01417-COA-
    R3-CV, 
    2018 WL 1920166
    , at *3 (Tenn. Ct. App. Apr. 24, 2018) (quoting Weakley Cnty.
    v. W. L. Carney, 
    14 Tenn. App. 688
    , 
    1932 WL 1295
    , *3-4 (Tenn. Ct. App. March 31,
    1932)). As the Roles-Walter Court proceeded to explain:
    The distinction between “nuisance” and “negligence” has been stated as
    follows:
    When defendant is the creator of a dangerous situation, his liability therefor
    is for a nuisance; but when defendant did not create a dangerous situation
    but is nevertheless under a duty to remove the danger, failure to do so
    involves a question of negligence. Another statement of the distinction is
    that, where the damage is the necessary consequence of just what defendant
    is doing, or is incident to the business itself or the manner in which it is
    conducted, the law of negligence has no application and the law of nuisance
    applies. It has also been said that the distinction lies in the fact that the
    creation or maintenance of a nuisance is the violation of an absolute duty,
    the doing of an act which is wrongful in itself, whereas negligence is the
    violation of a relative duty, the failure to use the degree of care required
    under the particular circumstances in connection with an act or omission
    which is not of itself wrongful.
    Roles-Walter, 
    2018 WL 1920166
    , at *4.
    - 30 -
    Plaintiffs therefore appear to concede in their brief that Wolf can only be liable for
    nuisance if Plaintiffs were able to establish that Wolf’s acts constituted misfeasance
    rather than nonfeasance—in other words, if Wolf were the creator of the dangerous
    condition. As previously explained, Wolf’s acts constituted mere nonfeasance, such that
    nuisance cannot be proven. We therefore conclude that summary judgment was properly
    granted in Wolf’s favor on Plaintiffs’ remaining claims.
    VI. Conclusion
    For the foregoing reasons, we affirm the trial court’s grant of summary judgment
    in Wolf’s favor concerning all of Plaintiffs’ claims. We remand this matter to the trial
    court for further proceedings consistent with this Opinion and collection of costs assessed
    below. Costs on appeal are assessed to the appellants, Allstate Property & Casualty
