MEMORANDUM OPINION AND ORDER
This civil action is before the Court on the Joint Motion to Dismiss for Lack of Subject Matter Jurisdiction or Failure to State a Claim or, in the Alternative, for Summary Judgment [Doc. 203], 1 filed by defendants WorleyParsons Corporation (“WorleyParsons”) and Geosyntec Consultants, Inc. (“Geosyntec”) (also referred to collectively as “defendants”). In the motion, defendants move to dismiss the consolidated class action complaint for lack of subject matter jurisdiction or for failure to state a claim, pursuant to Rule 12(b)(1) or Rule 12(b)(6) of the Federal Rules of Civil Procedure. Alternatively, defendants move for summary judgment on grounds that there is no genuine issue as to any material fact and defendants are entitled to judgment as a matter of law, pursuant to Rule 56(c) of the Federal Rules of Civil Procedure. Plaintiffs have responded in opposition [Doc. 225], and defendants have filed a reply [Doc. 240] to that response. For the reasons set forth herein, defendants’ motion will be granted and WorleyParsons and Geosyntec will be dismissed from this case.
I. Relevant Facts and Procedural Background
This case arises out of the December 22, 2008 failure of a coal ash containment dike at the Tennessee Valley Authority’s (“TVA’s”) Kingston Fossil Plant (the “KIF plant”), located in Roane County, Tennessee. Plaintiffs are owners of residential property in the vicinity of the KIF plant [Doc. 185, ¶ 46]. TVA, a federal corporate agency and instrumentality created by Congress and existing pursuant to the *572 Tennessee Valley Authority Act of 1933 (the “TVA Act”), 16 U.S.C. § 831, owns and operates the KIF plant [Id., ¶¶ 59-61, 77], WorleyParsons and Geosyntee are professional engineering contractors [Id., ¶¶ 17, 63-70]. Both provided engineering consultant services and/or advice to TVA, WorleyParsons from about 2004 through 2005, and Geosyntee from about 2004 through 2007. [Id.] 2
The KIF plant is a coal-fired electricity generation plant located on a peninsula at the confluence of the Clinch and Emory River embayments of the Watts Bar Reservoir in Roane County, Tennessee. The KIF plant produced coal ash, a byproduct of when coal is burned for electricity generation. Swan Pond, consisting of a main ash pond, a dredged ash disposal area, and a stilling pool, is located immediately north of the peninsula and served as the disposal site for the coal ash byproduct produced at the KIF plant. 3 Coal ash produced at the KIF plant was transported to the main ash pond as slurry through two sluice channels, one for coarser bottom ash and one for finer fly ash. When the slurry flowed through the sluice channels, the coarser bottom ash settled to the bottom. Sluice channels then removed the coarse bottom ash through mechanical means. The coarse bottom ash was then used for dike construction. The finer fly ash flowed through the sluice channels and into the main ash pond where it was dredged, normally by hydraulic means, and deposited into the ash disposal area, which was further divided into dredge cells by internal dikes. Excess water in the dredged ash disposal area drained back to the main ash pond and then to the stilling pool. The excess water flowed through thе discharge channel, into the KIF plant’s water intake channel, and into the Watts Bar Reservoir. Excess water also seeped down through the finer fly ash in the dredge cells and into the groundwater, which transported it into the Watts Bar Reservoir [Doc. 185, ¶¶ 16, 59, 72-110]. 4
In November 2003, a “blowout” occurred in a containment dike on one side of the dredged cell area [Doc. 185, ¶¶ 110-11, 117(b) ]. Following the blowout, TVA suspended dredging operations in the existing cells [Id.]. In 2004, TVA retained WorleyParsons 5 to determine the cause of the November 2003 blowout and to evaluate alternatives for the continued disposal of coal ash [Id., ¶ 117(a>(b), (g); Auchard, Doc. 43, ¶ 3]. WorleyParsons also conducted an engineering stability analysis of the dredge cell area and the adjoining main coal ash pond for TVA [Id., ¶ 112, 117(b); Auchard, Doc. 43, ¶ 4]. In June 2004, WorleyParsons reported the results of the stability analysis to TVA, including a recommendation to improve drainage in the ash ponds [Long, Doc. 140-3, pp. 19-20]. TVA *573 used WorleyParsons’s work to support its June 2004 application to the Tennessee Department of Environment and Conservation (the “TDEC”) for a modification of TVA’s Class II Landfill Permit (the “Landfill Permit”) for the KIF plant [Auchard, Doc. 43, ¶¶ 4-5; Auchard, Doc. 44-1, pp. 114, 105]. The TDEC approved TVA’s proposed modification of the Landfill Permit on September 12, 2006 [Auchard, Doc. 44-1, pp. 140, 242]. In 2004, TVA retained Geosyntec to conduct a peer review of WorleyParsons’ work, including the stability analysis and the associated recommendations [Doc. 185, ¶¶ 110-11, 117(b); Auchard, Doc. 43, ¶¶ 3-5; Auchard, Doc. 82-2, p. 11]. In a report to TVA, Geosyntec recommended an additional evaluation of bottom drainage alternatives for the KIF plant [Long, Doc. 140-3, p. 20],
In 2004, TVA directed a project team consisting of TVA personnel, WorleyParsons, and Geosyntec [Auchard, Doc. 44-2, pp. 68-69]. This team reviewed existing data, performed site investigation and parallel seepage calculations, and ran seepage calculation models [Id]. After the review, the team concluded that “the cause of the [November 2003] failure was piping and excessive seepage.” [Id., p. 69]. To “fix” the problem, the team proposed installing an additional trench drainage system [/&]. After the “fix” was installed, TVA resumed normal dredging operations on November 10, 2005 [Auchard, Doc. 43-1; Auchard, Doc. 82-2, p. 11]. WorleyParsons and Geosyntec assert that neither defendant performed the actual repair work [see Auchard, Doc. 43-1].
In November 2006, another blowout occurred at the same location as the November 2003 blowout [Doc. 185, ¶ 117(b); Auchard, Doc. 43, ¶ 6]. Following this blowout, TVA ceased dredging into the cells until April 9, 2007 [Doc. 185, ¶ 117(b); Auchard, Doc. 43, ¶ 6]. TVA retained Geosyntec to investigate the November 2006 blowout, to determine its cause, and to develop alternatives addressing seepage and disposal of the coal ash [Doc. 185, ¶ 117(b); Auchard, Doc. 43, ¶ 6; Auchard, Doc. 44-2, pp. 74-75]. After evaluating the alternatives identified by Geosyntec, TVA implemented localized toe drain improvements with additional monitoring, maintenance, and surface water improvements [Auchard, Doc. 43, ¶ 6; Auchard, Doc. 44-2, p. 76]. Normal dredging operations resumed in 2008 in accordance with the modified Landfill Permit [Auchard, Doc. 43, ¶¶ 6, 7; Auchard, Doc. 44-2, p. 12],
On December 22, 2008, a coal ash containment dike at the KIF plant failed [Doc. 185, ¶¶ 5-6, 132-35]. As a result of the dike failure, approximately 5.4 million cubic yards of coal ash sludge spilled from the 84-aсre containment area of the KIF plant to an adjacent area of about 300 acres, consisting of primarily the Watts Bar Reservoir, the Clinch and Emory Rivers, and government and privately owned shoreline properties [Auchard, Doc. 44, pp. 4-5; Auchard, Doc. 82, p. 12].
Following the coal ash spill, seven cases were filed against TVA. In the complaints, the plaintiffs allege that they reside, own property, and/or own businesses within the area of the coal ash spill.
See Mays v. TVA
It is now more than two years since the coal ash spill. Since the filing of the initial seven cases, more than fifty separate cases have been filed against TVA relating to the spill. Plaintiffs in this case were initially the plaintiffs in three of the first seven cases filed against TVA: Blanchard, et al. v. TVA Case No. 3:09-CV-09, Giltnane, et al. v. TVA, Case No. 3:09-CV-14, and Long, et al. v. TVA, et al., Case No. 3:09-CV-114. On February 25, 2010, these plaintiffs moved to consolidate their cases for all purposes, including discovery, class certification issues, and trial [see Doc. 133]. Plaintiffs also requested that the Court allow them to file consolidated complaint [see id.]. The Court granted plaintiffs’ requests [Doc. 183], and, on July 13, 2010, plaintiffs filed the consolidated class action complaint (the “complaint”) [Doc. 185].
In the complaint, plaintiffs assert negligence, gross negligence, and nuisance claims against TVA, WorleyParsons, and Geosyntec, and trespass, strict liability, negligence per se, and injunctive relief claims against TVA [Doc. 185, ¶¶ 178-217]. All plaintiffs seek monetаry damages and several plaintiffs seek the establishment of a medical monitoring fund or a supervised medical monitoring program [Id., ¶ 2], Plaintiffs also seek to represent three proposed classes, two property damage classes and a resident class [Id., ¶ 162]. The factual allegations and claims in the complaint are substantially similar to those brought in the other cases filed against TVA concerning the coal ash spill. One notable difference, however, is that plaintiffs in this case have brought suit against WorleyParsons and Geosyntec in addition to TVA. 6 No other plaintiff has, at present, asserted claims against these defendants. 7
On August 12, 2010, WorleyParsons and Geosyntec filed the instant motion to dismiss for lack of subject matter jurisdiction or failure to state a claim, or, in the alternative, for summary judgment [Doc. 203]. In the motion, defendants assert that plaintiffs’ claims against them should be dismissed for lack of subject matter jurisdiction because the engineering consultant advice and services they provided to TVA fall within the аreas TVA is entitled to discretionary function immunity. Defendants assert that they are entitled to share in TVA’s immunity based on the doctrine of derivative sovereign immunity. Defendants also assert that the complaint fails to allege sufficiently definite and plausible claims and fails to state claims for which relief may be granted. Alternatively, defendants assert that they are entitled to dismissal or summary judgment because plaintiffs’ nuisance, negligence, and gross negligence claims are deficient as a matter of law. Plaintiffs have responded in opposition to all defendants’ requests [Doe. 225]. Defendants have filed a reply [Doc. 240] to that response.
II. Standard of Review
A party may move to dismiss for lack of subject matter jurisdiction pursu
*575
ant to Federal Rule of Civil Procedure 12(b)(1). When a defendant challenges subject matter jurisdiction in a motion brought pursuant to Rule 12(b)(1), the plaintiff has the burden of proving jurisdiction to survive the motion.
Moir v. Greater Cleveland Reg’l Transit Auth.,
III. Analysis
A. The Discretionary Function Doctrine
As a general matter, the United States as sovereign is immune from suit except under certain limited circumstances in which it has waived that immunity.
See United States v. Mitchell,
Any claim ... based upon the exercise or performance or the failure to exercise or perform a discretionary function or duty on the part of a federal agency or an employee of the Government, whether or not the discretion involved be abused.
Id. § 2680(a).
The FTCA also explicitly excludes independent contractors from its scope.
[T]he term “Federal agency” includes the executive departments, the judicial and legislative branches, the military departments, independent establishments of the United States, and corporations primarily acting as instrumentalities or agencies of the United States, but does not include any contractor with the United States.
“Employee of the government” includes (1) officers or employees of any federal agency, members of the military or navy forces ... members of the National Guard ... and persons acting on behalf of a federal agency in an official capacity ... and (2) any officer or employee of a Federal public defender organization!.]
28 U.S.C. § 2671 (emphasis added). The FTCA is also limited to “civil actions on claims against the United States, for money damages, ... for injury or loss of property, or personal injury or death caused by the negligent or wrongful act or omission of any employee of the Government while acting within the scope of his office or employment!.]” Id. § 1346(b)(1) (emphasis added).
In the Court’s previous opinion concerning the discretionary function doctrine and its application to this litigation, the Court determined that TVA is entitled to immunity for certain allegations made by plaintiffs. The Court found that this immunity
*576
extends to plaintiffs’ allegations regarding TVA’s design and construction plans for the KIF plant, TVA’s decision to keep in operation the wet coal ash disposal system, and TVA’s post-spill clean-up, removal, and remediation conduct.
Mays,
[Negligent failure to inform or train TVA personnel in its policies and procedures for coal ash operations and management; negligent or inadequate performance by TVA personnel of polices and procedures; negligence in the construction and implementation of approved design and construction plans for the KIF plant and its surrounding impoundments; and negligent maintenance allegations.
Id. at 1021-22. 10
Notwithstanding the exclusion of independent contractors from the scope of the FTCA, defendants argue that they are entitled to derivative sovereign immunity based on TVA’s immunity under the discretionary function doctrine. Defendants assert that derivative sovereign immunity shields them from liability for their work and advice to TVA in connection with those areas in which TVA is entitled to discretionary function immunity. As support for their position, defendants rely primarily on
Yearsley v. W.A. Ross Constr. Co.,
*577 In response, plaintiffs contend that defendants are not entitled to derivative sovereign immunity under either Yearsley or Ackerson. Plaintiffs also contend that defendants have failed to demonstrate any entitlement to immunity based on the government contractor defense of Boyle. Plaintiffs also argue that they have alleged nondiscretionary conduct by defendants that falls outside the discretionary conduct the Court determined was shielded by the discretionary function doctrine and thus, even if this Court applies Yearsley and Ackerson or Boyle to the facts of this case, WorleyParsons and Geosyntec remain liable.
B. Yearsley and Boyle
In
Yearsley,
the U.S. Supreme Court considered whether a contractor that constructed dikes in the Missouri River pursuant to a contract with the federal government could be held liable for a taking of private property when the construction of the dikes produсed artificial erosion and washed away part of the plaintiffs’ riverside property.
[Authority to carry out the project was validly conferred, that is, if what was done was within the constitutional power of Congress, there is no liability on the part of the contractor for executing its will.
Id.
at 20-21,
Where an agent or officer of the Government purporting to act on its behalf has been held to be liable for his conduct causing injury to another, the ground of liability has been found to be either that he exceeded his authority or that it was not validly conferred.
Id.
at 21,
Defendants assert that Yearsley controls the analysis of the alleged liability of WorleyParsons and Geosyntec because the facts of this case concern the same issue— work performed by private contractors engaged in a public works project for the federal government. Defendants assert that Yearsley makes clear that if the federal government would not be held liable in performing challenged work, a contractor cannot be liable for performing the same work. Defendants acknowledge that the U.S. Court of Appeals for the Sixth Circuit has rarely applied Yearsley in the context of derivative sovereign immunity. They assert, however, that the Sixth Circuit has discussed the principles underlying Years ley in its discussions of contractors engaged in government work and that the relevant case law suggests that the Sixth Circuit would aрply derivative sovereign immunity to this case. 11
*578
Defendants also point to
Bennett v. MIS Corp.,
a recent case from the Sixth Circuit which discusses the government contractor immunity defense of
Boyle
and also refers to
Yearsley.
The plaintiff in
Boyle
was the father of a U.S. Marine helicopter copilot who drowned when his helicopter crashed off the coast of the United States.
Applying this two-step inquiry to the plaintiffs claim to determine whether his state law tort claims were preempted, the Supreme Court identified the “unique!] federal interest” as “the civil liabilities arising out of the performance of federal procurement contracts.”
Boyle,
The Supreme Court next turned to whether this conflict between the state tort law and the duty imposed by the contractor’s contract with the federal government was “significant.”
Boyle,
(1) the United States approved reasonably precise specifications; (2) the equipment conformed to those specifications; and (3) the supplier warned the United States about the dangers in the use of the equipment that were known to the supplier but not to the United States.
Id.
at 512,
In
Bennett,
the Sixth Circuit case, the court considered the
Boyle
defense in the context of federal officer removal jurisdiction under 28 U.S.C. § 1442(a)(1), the federal removal statute that requires a defendant to show a “colorable” federal defense for purposes of removal.
An earlier Sixth Circuit case that provides some guidance on how this circuit might apply
Yearsley
is
Gulf Refining Co. v. Mark C. Walker & Son Co.,
The
Gulf Refining
court, applying Tennessee law but also citing
Yearsley,
began its analysis by stating that “[t]here is no substantial controversy with respect to the legal principles applicable to the issues presented[,]” and the plaintiff “concedes that a contractor or subcontractor doing work for the government in accordance with its requirements is not liable to a
*580
third person for its incidental effect uрon his property, and that there is no presumption of negligence.”
Gulf Refining,
Along with the citation to
Yearsley,
the
Gulf Refining
court also cited
Chattanooga & Tennessee River Power Co. v. Lawson,
a Tennessee Supreme Court case involving a takings claim where the defendant was a contractor for the United States doing improvement work on the Tennessee River.
The reasoning underlying the holding of
Gulf Refining
and
Chattanooga & Tennessee River Power
was also evoked in
Green v. ICI America, Inc.,
a case in which the plaintiff sued to recover damages from the defendant, a contractor, for the alleged creation and maintenance of a nuisance at a plant installed by the U.S. Army but operated by the contractor.
The Fourth Circuit and the Fifth Circuit have considered the derivative sovereign immunity discussed in
Yearsley
and the government contractor defense discussed in
Boyle
and have noted the common federal interest relevant to each. In
Ackerson,
a case from the Fifth Circuit, the plaintiffs brought suit against the United
*581
States and government contractors alleging that dredging activities conducted near the Mississippi River Gulf Outlet had caused an amplification of a storm surge in the New Orleans region.
Both [Yearsley and Ackerson ] involve public-works projects. In both cases, the actions causing the alleged harm were taken pursuant to contracts with the federal government that were for the purpose of furthering projects authorized by Congress. And in both cases, the plaintiffs did not allege that the contractor defendant “exceeded his authority or that it was not validly conferred.”
Id.
(citing
Yearsley,
In
Butters v. Vance Inter., Inc.,
the Fourth Circuit cited
Yearsley
as exemplifying “well-settled law that contractors and common law agents acting within the scope of their employment for the United States have derivative sovereign immunity.”
In reviewing the facts and rationales of the previously discussed cases with the facts of this case, the Court finds the relevant case law to indicate that an analysis of this case applying the derivative sovereign immunity of
Yearsley
and
Ackerman
is appropriate. As the Sixth Circuit acknowledged in
Bennett,
the derivative immunity of
Yearsley
and the government contractor defense of
Boyle
address the same federal interest of a contractor’s performance of a government contract,
Bennett,
C. Derivative Sovereign Immunity and this Case
Under
Yearsley
and its progeny, a government contractor will not be liable when the authority to carry out the project was validly conferred and was within the constitutional power of Congress.
Yearsley,
WorleyParsons and Geosyntec assert that they are entitled to derivative sovereign immunity under Yearsley because they were contractors retained by TVA, an instrumentality of the federal government, for work on a project conducted pursuant to proper Congressional authorization. *583 WorleyParsons and Geosyntec assert that there are no allegations that either defendant failed to perform the contracts with TVA, performed outside the scope of the contracts, or that TVA refused to accept work related to the contracts. Defendants assert that plaintiffs’ allegations demonstrate that WorleyParsons and Geosyntec reported all studies, analyses, and recommendations to TVA, and that TVA had the ultimate authority to determine which, if any, of defendants’ advice and recommendations to follow and implement. Defendants also assert that WorleyParsons and Geosyntec did not make any misrepresentations to TVA regarding any work or studies done for TVA. Defendants assert that plaintiffs’ allegations against WorleyParsons and Geosyntec are in “precisely” the areas in which this Court has determined TVA is entitled to immunity under the discretionary function doctrine, including allegations pertaining to design, construction, and modification of the KIF plant, repairs, “fixes,” and “band-aids” implemented at the KIF plant, allegations pertaining to TVA’s decisions on coal ash storage, and allegations involving TVA’s decision and to keep in operation the wet coal ash storage system.
Plaintiffs contend that WorleyParsons and Geosyntec’s activities with respect to the KIF plant do not constitute a governmental function or a “uniquely federal interest” but were actions taken pursuant to TVA’s commercial function [Doc. 185, ¶ 62]. Plaintiffs assert that WorleyParsons and Geosyntec were neither authorized by Congress nor executing its will in their work for TVA [Doc. 225, p. 22]. Plaintiffs also assert that the challenged conduct does not fall within the discretionary function doctrine because WorleyParsons and Geosyntec were “actively involved in the use, maintenance, and upkeep of the KIF facilities, including the ‘due care’ related activities recognized by this Court as not being subject to discretionary function immunity.” [Id., p. 16]. Plaintiffs also assert that WorleyParsons and Geosyntec violated professional engineering standards and knew or should have known that the wet coal ash systеm at the KIF plant was unsafe and likely to fail [Doc. 185, ¶ 17],
The TVA Act designates TVA as “an instrumentality and agency” of the United States.
Hill v. United States Dep’t of Labor,
*584 Plaintiffs have asserted that TVA owns, operates, maintains, and inspects the KIF plant [Doc. 185, ¶¶ 16, 59, 77, 79], Plaintiffs have also asserted that WorleyParsons and Geosyntec were contractors retained by TVA to provide engineering and consulting services and advice to TVA in connection with the design, inspection, maintenance, repair, and operation of the wet coal ash disposal system at the KIF plant [Id., ¶¶ 63-70]. Plaintiffs have not disputed that TVA had the authority, pursuant to an act of Congress, to own and operate the plant for electric power purposes [Id., ¶¶ 60, 61, 72, 73, 77], Plaintiffs have not disputed that Congress had the constitutional authority to delegаte to TVA the authority to produce electricity by way of coal-fired plants or to maintain electricity-production facilities. Plaintiffs have also not disputed that TVA had the authority to award contracts to WorleyParsons and Geosyntec for work on various projects at the KIF plant. Finally, plaintiffs have not disputed that WorleyParsons and Geosyntec’s contracts with TVA were for a function TVA was authorized to perform— the production of coal-fired electricity and the maintenance of a coal ash storage and disposal system [Id., ¶¶ 60, 61, 72, 73, 77].
Accordingly, the Court does not agree that WorleyParsons and Geosyntec were not authorized by the government or were not executing the government’s will through defendants’ contracts and work for TVA. There is no allegation that Congress lacked the authority to give TVA the power to produce electricity, no allegation that TVA lacked the authority to engage in electric power production through coal-fired plants at the KIF plant, no allegation that TVA lacked the authority to retain WorleyParsons and Geosyntec for consulting and other services, and no allegation that either defendant exceeded the authority TVA gave to each under those contracts. Thus, the Court finds that WorleyParsons and Geosyntec had “validly conferred” authority to perform work at the KIF plant.
See Yearsley,
According to plaintiffs, WorleyParsons and Geosyntec were “hired by and working on behalf of TVA with regard to the KIF facility, including the design, inspection, maintenance, repair, and operation of its impoundments and dredge cells[.]” [Doc. 185, ¶¶ 65-71]. Also according to plaintiffs, WorleyParsons and Geosyntec knew about the risks and hazards associated with the “construction, build-up, and material properties of the KIF coal ash impoundment, but negligently failed to follow well-established engineering standards.” [Doc. 225, pp. 5-6; Doc. 185, ¶¶ 17, 99-130; Doc. 226-1, pp. 2-6]. Specifically, plaintiffs allege that WorleyParsons and Geosyntec: failed to adequately advocate and insure thаt TVA stopped adding wet coal ash material to the coal ash disposal facilities despite evidence of problems; acquiesced to TVA’s decisions not to follow substantive recommendations which would have made the KIF plant safer; misrepresented safety issues; failed to inform or disclose to relevant agencies the risks and hazards associated with the impoundment’s construction, build-up, and materials; recommended and implemented low-cost “fixes” and “band-aids” which exacerbated risks; and failed to investigate the underlying causes of the blowouts despite evidence of “red flags.” [Doc. 185, ¶ 17, 99-130; Doc. 226-1, pp. 2-6],
WorleyParsons and Geosyntec assert that these allegations are in precisely the areas in which TVA is entitled to immunity under the discretionary function doctrine and if TVA would not be liable for such conduct, defendants cannot be held liable for performing the same work.
In the Court’s previous opinion concerning the extent of TVA’s immunity under *585 the discretionary function doctrine, the Court stated that:
In the years prior to the coal ash spill, TVA mаde a policy decision, grounded in considerations of public policy, to have a wet coal ash storage and disposal facility. In conjunction with this overarching policy decision, TVA made a series of policy decisions regarding where to locate the coal ash disposal facilities and the design and construction of the facilities. TVA also made policy decisions after the Swan Pond facilities were in operation as to what polices and procedures would govern the coal ash disposal, decisions such as whether to implement modifications or changes to the facilities and whether to continue disposing of the coal ash with a wet storage system. Several of Plaintiffs’ tort claims, however, challenge conduct apart from these policy decisions.
Mays,
In the course of making these policy decisions, TVA drew, in part, upon the work, studies, advice, and recommendations of WorleyParsons and Geosyntec. While plaintiffs have couched their allegations against WorleyParsons and Geosyntec in terms of defendants’ failure to exercise due care, failure to follow engineering best practices, and failure to advocate or recommend different or “safer” manners of design, redesign, modifications, fixes, and coal аsh disposal methods, such allegations clearly challenge the policy decisions by TVA that are protected by the discretionary function doctrine. The selection of an appropriate design, appropriate modifications or fixes, and appropriate policies and procedures for coal ash disposal, are decisions involving not merely engineering analysis, but judgment as to the balancing of many technical, budgetary, corporate, and even social considerations, including the need for and level of electric power production, costs, safety factors, and environmental considerations and developments. While defendants’ recommendations and TVA’s ultimate decisions may have resulted in designs, repairs, or operational policies and procedures that were not comprehensive or were otherwise inappropriate, “[e]ven the negligent failure of a discretionary government policymaker tо consider all relevant aspects of a subject matter under consideration does not vitiate the discretionary character of the decision that is made.”
Myslakowski v. United States,
The Court has thoroughly reviewed the allegations in the complaint and in the related pleadings. In doing so, the Court cannot conclude that plaintiffs’ allegations against WorleyParsons and Geosyntec encompass conduct apart from the design of the KIF plant, its redesign and expansions, the corrective measures and repairs taken or not taken, and TVA’s ash handling and disposal policies, procedures, and operations. While plaintiffs have alleged a lack of “due care” and negligent conduct by defendants in these areas, such allegations challenge the substance and wisdom of the recommendations by WorleyParsons *586 and Geosyntec that went into TVA’s actual discretionary policy decisions.
Further, and as indicated below, plaintiffs’ “due care” and negligence allegations are not thе type of allegations described by the Court in its previous opinion as the type which may survive the discretionary function doctrine:
[O]nce TVA determined and implemented the policy decision to have a coal ash storage facility at Swan Pond, TVA had an obligation to continue and pursue that policy decision in a non-negligent manner. Following or acting pursuant to such policies and procedures was not a matter of discretion—the issues raised by Plaintiffs’ claims in these cases are not solely questions of social wisdom, but also of negligence, not questions of political or economic practicability, but of due care. To this end, the Court recognizes that several of Plaintiffs’ claims encompass allegations that TVA should have converted the Swan Pond facility to a dry coal ash disposal system, that TVA should have constructed the Swan Pond facilities in a different manner, or that the policies and procedures TVA had in place were improper. If these were Plаintiffs’ sole claims against TVA then the discretionary function [doctrine] might very well shield TVA from all liability.
The Court also stated that:
[Sjeveral of Plaintiffs tort claims fall within the category of cases which address the actual implementation of a particular policy decision that is itself protected by the discretionary function doctrine. That is, once a government agency makes a policy decision protected by the discretionary function doctrine, the agency must then proceed with care in the implementation of that decision.
Mays,
Thus, the Court agrees with Geosyntec and WorleyParsons that plaintiffs’ allegations against these defendants fall within those arеas to which the Court has determined that TVA is entitled to immunity under the discretionary function doctrine. Accordingly, under Yearsley, if TVA would not be liable for the challenged conduct and/or decisions, Geosyntec and WorleyParsons cannot be held liable for then-conduct in regard to the same challenged conduct and/or decisions. Defendants, Geosyntec and WorleyParsons, are therefore, entitled to derivative sovereign immunity and dismissed from this case for lack of subject matter jurisdiction.
IV. Conclusion
For the reasons stated above, defendants’ Joint Motion to Dismiss for Lack of Subject Matter Jurisdiction or Failure to State a Claim or, in the Alternative, for Summary Judgment [Doc. 203] is GRANTED because Geosyntec and WorleyParsons are entitled to derivative sovereign immunity. Accordingly, all plaintiffs’ claims against Geosyntec and WorleyParsons are DISMISSED and these defendants are DISMISSED from this case.
IT IS SO ORDERED.

. "In the years prior to the coal ash spill, TVA made a policy decision, grounded in considerations of public policy, to have a wet coal ash storage and disposal facility. In conjunction with this overarching policy decision, TVA made a series of policy decisions regarding where to locate the coal ash disposal facilities and the design and construction of the facilities. TVA also made policy decisions after the Swan Pond facilities were in operation as to what polices and procedures would govern the coal ash disposal, decisions such as whether to implement modifications or changes to the facilities and whether to continue disposing of the coal ash with a wet storage system. Several of Plaintiffs’ tort claims, however, challenge conduct apart from these policy decisions.”
Mays,
."Neglect, ignoring policies and procedures, failing to implement corrective measures or modifications under those policies, or the failure to have in place any policies and procedures governing coal ash disposal, are not the type of decisions or conduct protected by the discretionary function doctrine.”
