MEMORANDUM AND ORDER

The present lawsuit challenges several changes California has implemented with respect to its payment for services provided to developmentally disabled individuals under the federally funded Medicaid program.

Plaintiffs are the ARC of California (“ARC”) and the Cerebral Palsy Association of San Diego (“CPA”). 1 Arc is a statewide organization comprised of individuals with intellectual and developmental disabilities (“I/DD”), their families and their home and community-based service providers. CPA is an non-profit organization serving the needs of individuals with cerebral palsy in San Diego and is affiliat *1116 ed with the national cerebral palsy association.

Plaintiffs’ Motion for Preliminary Injunction is now before this Court. That Motion seeks to enjoin California from continuing to implement a 1.25 percent pay rate reduction to disabled service providers passed by the Legislature in 2012, as well as enforcement of mandatory unpaid holidays for providers and a “half day billing” rule in which providers cannot be reimbursed for a full day if their client chooses to leave early for whatever reason, even if the provider has to maintain a full day slot for providing services to the individual.

Injunctive relief is sought pursuant to the complaint under three federal sources. Plaintiffs first seek to enjoin the State’s billing reductions under the Medicaid Act. They alternatively seek an injunction under both the Americans with Disabilities Act of 1990, 42 U.S.C. § 12101 et seq. (“ADA”) and the Rehabilitation Act of 1973, 29 U.S.C. § 794 , et seq. (“Rehabilitation Act”).

BACKGROUND

Medicaid is a cooperative federal state program designed to provide, pursuant to the Medicaid Act, federal assistance to participating states for the costs of providing medical treatment and services to the poor, elderly and disabled. 42 U.S.C. § 1396 . Although state participation in funding available from Medicaid is voluntary, if a state does participate it must comply with the Medicaid Act and its implementing regulations promulgated by the Secretary of Health and Human Services (“HHS”). Wilder v. Va. Hosp. Ass’n, 496 U.S. 498, 502 , 110 S.Ct. 2510 , 110 L.Ed.2d 455 (1990). Administration of the Medicaid program, however, is entrusted by HHS to CMS.

A state choosing to participate in the Medicaid program must prepare and submit a “State Plan” for federal approval that includes a comprehensive written statement describing the nature and scope of its Medicaid program. A State Plan must also contain assurances that it will be administered in accordance with the dictates of Medicaid law. Wilder v. Virginia Hospital Assn., 496 U.S. 498, 502 , 110 S.Ct. 2510 . Additionally, if a state wants to change its Medicaid plan once approved, it must obtain approval from CMS in the form of a so-called State Plan Amendment (“SPA”) to do so. Exeter Memorial Hosp. Ass’n v. Belshe, 145 F.3d 1106, 1108 (9th Cir.1998).

Among the prerequisites to participation in the Medicaid program is compliance with the requirements set forth within 42 U.S.C. § 1396 (a)(30)(A) (“Section 30(A)”) which requires, inter alia, that payment for services to the disabled be consistent with “efficiency, economy, and quality of care.” Additionally, in 1981, Congress responded to the large percentage of Medicaid resources being used for long-term institutional care for the disabled by authorizing a home and community-based services (“HCBS”) waiver program. 42 U.S.C. § 1396n. Development of that program was prompted by studies showing that many disabled persons then residing in institutions could in fact live at home, or in the community, if additional support services were available. The HCBS waiver program is designed to make such services available to those who would benefit from less restrictive care, but who otherwise would be eligible for Medicaid benefits only in an institutional setting. Id. at § 1396n(c)(1).

In order to obtain a waiver, a State has to certify that its treatment program is cost-neutral in the sense that the costs of providing services to individuals enrolled in the waiver program will be less than or equal to in the cost of institutional care. *1117 Id. at § 1396n(c)(2)(D); Sanchez v. Johnson, 416 F.3d 1051, 1054 (9th Cir.2005).

States must submit their waiver application to the Centers for Medicare and Medicaid Services (“CMS”), the federal agency responsible for administering Medicaid based programs, for review. CMS approval of a submitted application “waives” three requirements of the overall federal Medicaid statute: 1) statewideness; 2) comparability of services; and 3) income and resource rules. Id. at § 1396n(c)(3). All other requirements of the Medicaid Act are deemed satisfied upon CMS’s approval of the waiver request 42 C.F.R. § 400.200 ; 430.25(g)(1). In the present case, CMS approved California’s waiver program, including the rates paid to regional centers responsible for delivering care, on March 26, 2012, for an additional term of five years.

Unlike other states, California has made its own commitment under the so-called Lanterman Act to pay for services and support to the disabled from its own general funds. The Lanterman Act (Cal. Welf. & Inst.Code § 4500 et seq.) was enacted in 1967, some fourteen years before implementation of the federal HCBS waiver program, to prevent or minimize the institutionalization of developmentally disabled persons. In order to accomplish that objective, disabled persons under the Lanterman Act are entitled to services and supports at California’s expense. Ass’n for Retarded Citizens v. Dept. of Developmental Servs., 38 Cal.3d 384, 391 , 211 Cal.Rptr. 758 , 696 P.2d 150 (1985). Because of that right, enrollment by Californians in the waiver program is voluntary and serves primarily as a vehicle for the state to recoup expenses it would already have been obligated to pay under the Lanterman Act (the Medicaid matching funds California receives covers about half the costs of services the regional centers provide to the disabled community). See Sanchez v. Johnson, 416 F.3d at 1065 . Many of the disabled persons eligible for services under the Lanterman Act in fact lack the extent of impairment qualifying them for federal funds under the HCBS waiver program. Id.

In California, the Department of Health Care Services (“DHCS”) is the state agency responsible for administering the federal Medicaid program, known as Medi-Cal in California. The California Department of Developmental Services (“DDS”), however, is responsible for coordinating the provision of services and supports for individuals with developmental services under both the Lanterman Act and for those covered under the HCBS waiver. DDS is accordingly charged with monitoring the 21 regional centers in California who contract our services for compliance with both federal and state law, and to ensure that high quality services and supports are being provided. Cal. Welf. & Inst.Code §§ 4434(a, b), 4500.5(d), 4501. DDS is further charged with promoting uniformity and cost-effectiveness in the operation of regional centers. Ass’n for Retarded Citizens, 38 Cal.3d at 389 , 211 Cal.Rptr. 758 , 696 P.2d 150 . Despite this mandate, however, DDS’ role “does not extend to the manner in which [regional] centers provide services or in general operate their programs.” Id. at 389-90 , 211 Cal.Rptr. 758 , 696 P.2d 150 . Instead, the regional centers themselves determine eligibility, assess needs, and coordinate the provisions of services to individuals within a defined geographic area. Cal. Welf. and Inst.Code § 4620. The centers do this through the preparation of an individual program plan («ipp”) for eacjj disabled client and provides services pursuant to the IPP Although Plaintiffs take issue with the budget cuts prompted by California’s recent fiscal crisis, according to the State, any regional center/provider contract must include a provision that payment under the *1118 contract is dependent upon the availability of state funds, and that vendors must agree to accept rates established, revised or adjusted by the Department as payment in full for all services provided. Cal. Code of Regs, Title 17, §§ 50609, 54326.

Despite that admonition, Plaintiffs challenge four bills, as enacted by the California Legislature since 2009, that operate to reduce of freeze rates to HCBS providers. Using payment levels from 2003, the Legislature initially enacted a three percent reduction from those rates effective February 1, 2009, through June 30, 2010. That reduction, along with an additional 1.25 percent cut, was ultimately extended through June 30, 2012.

After June 30, 2012, the reimbursement reduction was decreased to only 1.25 percent, where it remains at present. In addition, as indicated above, another bill sets forth 14 unpaid holidays for which vendors are not reimbursed for their services. Finally, the so-called half-day billing rule limited regional centers to payment for only a half day if a patent was present less than 65 percent of a program day. The State maintains that those reductions apply to all disabled individuals irrespective of whether they qualify for services under the waiver or under the Lanterman Act.

It should also be noted that irrespective of these reductions, regional centers can still obtain an exemption from reduced payments (but not apparently for the holiday or half-day rule limitations) upon a showing that a non-redueed payment is necessary to protect the health and safety of the individual from whom the services and supports are proposed to be purchased. SB 853, AB 104. Moreover, patients themselves (or their representatives) can avail themselves of a tiered appeal process should they believe that the services being provided are inadequate. Finally, consumers can submit a complaint directly to DDS if their particular problem does not fit within other grievance mechanisms.

Plaintiffs now seek to enjoin California’s reimbursement reduction measures on grounds that those measures were taken without complying with Medicaid’s procedural and substantive requirements under federal law. Plaintiffs contend that they demonstrate a probability of success on their arguments in that regard, and claim that irreparable harm is shown because failing to provide the disabled with services commensurate with their particular needs subjects them both to a substantial risk of harm and an increased risk of hospitalization. Plaintiffs make a similar argument with respect to their Rehabilitation Act and ADA claims, arguing that failure to provide adequate access constitutes discrimination on the basis of disability.

Plaintiffs correctly point out that the Supreme Court, in Olmstead v. L.C. ex rel. Zimring, 527 U.S. 581 , 119 S.Ct. 2176 , 144 L.Ed.2d 540 (1999), found that Title II of the ADA requires states to provide community-based treatment, rather than institutionalization, where such treatment is appropriate and can be reasonably accommodated. Moreover, the Ninth Circuit, in Townsend v. Quasim, 328 F.3d 511, 516-17 (9th Cir.2003,) similarly found, under an Olmstead analysis, that failure to provide Medicaid services to the disabled in a community-based setting is a form of discrimination on the basis of disability.

STANDARD

The issuance of preliminary injunctive relief is an extraordinary remedy, and Plaintiffs have the burden of demonstrating the propriety of such a remedy by clear and convincing evidence. See Mazurek v. Armstrong, 520 U.S. 968, 972 , 117 S.Ct. 1865 , 138 L.Ed.2d 162 (1997); Gran *1119 ny Goose Foods, Inc. v. Teamsters, 415 U.S. 423, 442 , 94 S.Ct. 1113 , 39 L.Ed.2d 435 (1974). Following the Supreme Court’s decision in Winter v. Natural Resources Defense Council, 555 U.S. 7 , 129 S.Ct. 365 , 172 L.Ed.2d 249 (2008), the party requesting such relief must show that “he is likely to succeed on the merits, that he is likely to suffer irreparable harm in the absence of preliminary relief, that the balance of equities tips in his favor, and that an injunction is in the public interest.” Stormans, Inc. v. Selecky, 586 F.3d 1109, 1127 (9th Cir.2009) (quoting Winter, 129 S.Ct. at 374 ). Alternatively, under the so-called sliding scale approach, as long as the Plaintiffs demonstrate the requisite likelihood of irreparable harm and show that an injunction is in the public interest, a preliminary injunction can still issue so long as serious questions going to the merits are raised and the balance of hardships tips sharply in Plaintiffs’ favor. Alliance for Wild Rockies v. Cottrell, 2010 WL 2926463 at *4-7 (9th Cir. July 28, 2010) (finding that sliding scale test for issuance of preliminary injunctive relief remains viable after Winter).

Plaintiffs argue that the Ninth Circuit has found injunctive relief to be appropriate where a state reduces payments to Medicaid providers without complying with Medicaid requirements. Orthopaedic Hospital v. Belshe, 103 F.3d 1491, 1496 (9th Cir.1997). Plaintiffs further claim that injunctive relief under the ADA and the Rehabilitation has been ordered where state action places disabled individuals at a serious risk of institutionalization by reducing access to community-based care. See M.R. v. Dreyfus, 663 F.3d 1100 (9th Cir.2011).

ANALYSIS

A. Success on the Merits

With respect to California’s noncompliance with Medicaid law, Plaintiffs basically contend that the State failed to comply with the rate setting requirements set forth in 42 U.S.C. § 1396a(a)(30)(A) (“Section 30(A)”). Section 30(A) requires that payment for services must be “consistent with efficiency, economy, and quality of care.” The Ninth Circuit, in its Orthopaedic decision, interpreted this statutory language as meaning that “payments must be sufficient to enlist enough providers to provide access to Medicaid recipients.” Orthopaedic, 103 F.3d at 1496 . The Orthopaedic case further found that DHCS “must set hospital outpatient reimbursement rates that bear a reasonable relationship to efficient and economical hospital’s costs of providing quality services,” and that in making such determinations it must rely on “responsible cost studies” that “provide reliable date as a basis for its rate setting.” Id. Plaintiffs claim that the State has done nothing to ascertain whether the challenged payment reductions are consistent with federal rate-setting standards and requirements.

Defendants take issue with Plaintiffs’ argument in several ways. First, they argue that Section 30(A), while applicable to Medicaid in general, nonetheless does not apply to an HCBS waiver like that at issue here.

According to Defendants, the HCBS waiver regulations themselves appear to exempt waiver applicants from the Section 30(A) requirements. Second, Defendants point to a recent Ninth Circuit decision, Managed Pharmacy Care v. Sebelius, 716 F.3d 1235 (9th Cir.2013) 2 that they claim *1120 is controlling here. Managed Care found that where, as here, CMS approves state provisions that include reimbursement reductions, that approval is entitled to so-called Chevron deference.

Section 30(A) states that a state plan for medical assistance under the Medicaid Act must

42 U.S.C. § 1396a(a)(30)(A) (emphasis added).

This language, as the Ninth Circuit recognizes, is “broad and diffuse”. Sanchez v. Johnson, 416 F.3d at 1060 . By using terms like “consistent,” “sufficient,” “efficiency,” and “economy,” without describing the specific steps a state must take in order to meet such standards, the amorphous language of the statute indicates that agency expertise is relevant in determining its application, Managed Care, 716 F.3d at 1247-48 , citing Douglas v. Indep. Living Ctr. of S. Cal., — U.S. -, 132 S.Ct. 1204, 1210 , 182 L.Ed.2d 101 (2012).

In Orthopaedic, the Ninth Circuit interpreted the statutory mandate of Section 30(A) as requiring Medicaid reimbursement rates to “bear a reasonable relationship to efficient and economical” hospital costs for providing quality services.

To do this, the Orthopaedic court reasoned, the state had to “rely on responsible cost studies, its own or others that provide reliable data as a basis for its rate setting.” 103 F.3d at 1496 . As Defendants note, this interpretation of Section 30(A) as requiring cost studies is not found in the statute itself and was made in the absence of any agency approval for the reimbursement reductions that the court considered.

The Managed Care decision looks at the issue anew under circumstances where CMS had in fact approved reimbursement reductions incorporated within a proposed State Plan Amendment (“SPA”) for the provision of Medicaid services in general. Plaintiffs in that case argued that because cost data had not been provided in the SPA submitted by California, the Ninth Circuit’s prior Orthopaedic decision mandated that any reimbursement reduction approval be voided. Even the Orthopaedic court, however, recognized that “our standard of review might have been different had the agency spoken on the issue.” See Managed Care, 716 F.3d at 1245 . Significantly, in Managed Care, unlike Orthopaedic, CMS did explicitly approve the SPA at issue, even though no cost studies had been submitted. Managed Care court held that the agency’s decision in that regard was entitled to deference, and found that California is not required to conduct cost studies or follow any specific procedural steps before reducing Medicaid reimbursement rates under Section 30(A). Managed Care, 716 F.3d at 1240-41 .

Defendants argue that because CMS in this case approved the HCBS waiver submitted by California, then Managed Care disposes of Plaintiffs’ seminal claim that the reimbursement reductions run afoul of Medicaid law. Plaintiffs, on the other hand, try to distinguish Managed Care on grounds that it involved approval of an SPA amendment, not an HCBS waiver and should, accordingly, be distinguishable. Plaintiffs further contend that CMS lacked any real cost of service information, and *1121 that any approval without that information was in error.

The fact that Managed Care involved an SPA amendment and the present case revolves around an HCBS waiver is not of consequence.

In both instances, CMS approval for state Medicaid programs involving reimbursement reductions is involved. Moreover, with respect to whether adequate information was presented to CMS with respect to cost was presented, in accordance with Managed Care, that question is superseded by the fact that CMS approved the waiver. The evidence indicates that California submitted a waiver application in excess of 200 pages. That application was required to provide information about 1) methods for assessing financial accountability and cost-neutrality; 2) information regarding the utilization of services by consumers, including the number of participants and information regarding the utilization of specified services; and 3) assurances that the state will protect the health and welfare of beneficiaries, including assurances that the state will provide ongoing assessment of a consumer’s need for services, and a plan for evaluation. 42 C.F.R. §§ 441.302-303 . While Plaintiffs contend that CMS never required any specific information with regard to rates or rate methodology in the HCBS waiver, CMS nonetheless approved the waiver application on the basis of the detailed application that was submitted. Significantly, to counter any claim that insufficient information was in fact provided, CMS also has authority to revoke an HCBS waiver application at any time if it determines, post-approval, that a state is not in compliance. Id. at §§ 430.25, 441.300-310.

Given these requirements, I believe that CMS’ determination in approving California’s 2012 waiver application is entitled to Chevron deference just as the SPA approval was so deemed in Managed Care. To the extent that CMS approved the waiver in error for any reason, that shortcoming should be brought to CMS’ attention directly by way of a claim under the Administrative Procedures Act, rather than through the present lawsuit against California. Douglas v. Indep. Living Ctr. of S. Cal., 132 S.Ct. at 1210 .

Secondly, and just as importantly, the cost study information that Plaintiffs argue should have been included does not appear to have been required for a waiver in any event. 42 C.F.R. § 441.303 (g) indicates that cost analysis is optional, rather than required, in the context of waiver applications. As the regulations state: “The State, at its option, may provide for an independent assessment of its waiver that evaluates the quality of care provided, access to care, and cost neutrality.” Id. Significantly this language for all intents and purposes incorporates the considerations set forth in Section 30(A). By expressly indicating that such information is not mandatory, a persuasive argument can be made that Section 30A) compliance is not required, just as Defendants contend. At the very least, that interpretation of the regulations is a reasonable one. Agency interpretation and application of its own regulations is entitled to deference. Chase Bank USA v. McCoy, — U.S. -, 131 S.Ct. 871, 880-82 , 178 L.Ed.2d 716 (2011); Auer v. Robbins, 519 U.S. 452, 461 , 117 S.Ct. 905 , 137 L.Ed.2d 79 (1997) (federal agency’s interpretation of regulation entitled to deference unless “plainly erroneous or inconsistent with the regulation”).

Finally, with respect to Plaintiffs’ claims under the ADA and the Rehabilitation Act, the papers submitted in support of this Motion make it clear those claims also hinge on Defendants’ alleged noncompliance with the Rule 30(A) factors, and the alleged discriminatory effect this has on individuals qualifying for services *1122 under the HCBS waiver. 3 Plaintiffs’ Opening Points and Authorities, for example, state unequivocally that by denying HCSB beneficiaries the protections of Section 30(A), the State is engaging in discrimination on the basis of disability” in contravention of both the ADA and the Rehabilitation Act. ECF No. 83-1, 17:7-9.

Plaintiffs’ reply reiterates this position by phrasing the salient issue under both the ADA and Rehabilitation Act as whether the state may permissibly deny HCBS participants “the statutory protections of Section 30(A). ECF No. 93: 2:4-10 Because Plaintiffs are unlikely to prevail on their claims predicated on Section 30(A) for the reasons stated above, their ADA and Rehabilitation Act claims which similarly turn on alleged violations of Section 30(A) are no more likely to be successful.

For all of the above articulated reasons, Plaintiffs are unlikely to prevail on the merits. Therefore, this factor weighs against granting any injunctive relief. In fact, since under either test for granting a preliminary injunction a likelihood of success is required, that shortcoming alone precludes the requested relief.

B. Irreparable Harm

Even if Plaintiffs could overcome the hurdle of demonstrating a likelihood of success, which I believe they cannot, it is by no means certain whether Plaintiffs could satisfy the irreparable harm requirement for purposes of qualifying for a preliminary injunction. A mere “possibility” of irreparable injury is insufficient to support an injunction. Winter, 129 S.Ct. at 375 . Further, a “plaintiffs long delay before seeking a preliminary injunction implies a lack of urgency and irreparable harm.” Oakland Tribune, Inc. v. Chronicle Pub. Co., Inc., 762 F.2d 1374 , 1377 (9th Cir.1985).

Plaintiffs have submitted eighteen declarations from providers, seven declarations from parents, and two declarations from experts detailing the alleged risk of harm resulting from the continuing reimbursement cuts. They argue that after nearly ten years of frozen rates (since 2003), additional payments reductions (both directly and indirectly), are driving providers towards insolvency, therefore destabilizing and degrading the delivery of services and jeopardizing the health, safety and welfare of innumerable disabled individuals and family members.

The declarations from family members document the alleged decrease in access and quality of services as well as the real consequences those shortcomings have on the disabled as well as their families. Plaintiffs claim that the cutbacks are more disproportionately felt by individuals with the most severe and debilitating conditions, since those conditions usually require a higher level and/or quality of care.

Defendants contend that the requisite harm is not presented by the declarations since they focus on potential harm which may occur in the future rather than concrete harm that is either happening now or will happen imminently if the requested injunctive relief does not issue. According to Defendants, the harm identified is gen *1123 eralized, amorphous, and conjectural in nature. Plaintiffs not surprisingly take issue with that characterization, arguing that they should not have to wait until catastrophic harm occurs before they are entitled to stop what they allege are harmful and discriminatory practices against disabled individuals.

Plaintiffs point to the Ninth Circuit’s decision in M.R. v. Dreyfus, 697 F.3d 706 (9th Cir.2011), where a preliminary injunction was granted with respect to disability service payment reductions, as supportive of their position. In Dreyfus, however, unlike the present case, twelve individual plaintiffs presented substantial evidence of serious risk of institutionalization caused by the regulations at issue. Plaintiffs have not shown that any consumer has failed to receive services and supports identified in his or her IPP as a result of the statutory payment reductions. See id. at 726-727.

Although the declarations do appear to recite program cuts and effects upon individuals that may amount to more than mere speculation, it is uncontroverted that the payment reductions at issue were in place more than two years before suit was filed on behalf of Plaintiffs in 2011. In addition, since 3.0 percent cutbacks in place since 2009-10 ultimately sunsetted in June of 2012, leaving only 1.25 percent in reimbursement reductions currently in place, Plaintiffs are now receiving more reimbursement than at any time since 2009.

Plaintiffs counter by arguing that the reductions were initially billed as temporary, and that it was only after they were extended three times’that they realized this was not the case and they, consequently, in desperation, filed -the present lawsuit. Nonetheless, the fact that Plaintiffs unquestionably waited some two years before commencing this action weighs against irreparable harm under the Oakland Tribune case cited above.

Another factor that must be mentioned is the fact that under the terms of the reimbursement reduction legislation at issue, regional centers have the right to apply for an exemption from any reduced payments. If it is demonstrated that an exemption is necessary to protect a consumer’s health or safety, the DDS is authorized to grant such exemptions. Brian Winfield Decl., ¶¶ 15-16. 4 Defendants claim there is no evidence that any exemptions have been sought and denied by any regional center. Plaintiffs argue in response, however, that the exemptions are limited in scope because by their terms they are limited only to concerns of “health and safety” rather than to a consumer’s overall welfare and well-being. Plaintiffs also argue that the exemption applies only to the percentage payment reductions themselves, and offer no avenue for alleviating the mandatory holiday and half-day billing provisions also targeted by this lawsuit. Nonetheless Plaintiffs’ failure to demonstrate that any exemption, has been sought bears adversely on the claimed irreparable harm.

Similarly, consumers themselves may invoke a fair hearing process to resolve any dispute they have with regard to support and services provided by the regional centers. Such an appeal has to be filed within 30 days following notification of a decision or action with which the consumer is dissatisfied, and includes an escalated process *1124 starting with a voluntary informal meeting, and proceeding as necessary to mediation and then to full hearing. Winfield Decl., ¶¶ 6-8.

Significantly too, with the exception of two consumers, Joseph Napoliello and Megan Alexander, Plaintiffs have presented no evidence that any fair hearing process has been sought with regard to the reductions at issue. Even with regard to Napoliello and Alexander, their complaints were resolved at the initial informal level inasmuch as the requested actions (additional supportive living services and a full-sized hospital mattress, respectively) were granted.

Also militating against the requisite irreparable harm is evidence presented by Defendants indicating that the challenged payment reductions have not resulted in an increase in the risk of serious harm to disabled consumers, or an increased risk of institutionalization. Brian Winfield, who is a Deputy Director for DDS charged with monitoring and oversight over California’s 21 regional centers, indicates that the number of disabled individuals institutionalized in licensed state hospitals has steadily declined between June 28, 2006, and June 2012 (from 2.956 to 1,686), despite the challenged reimbursement cuts which Plaintiffs allege has increased the likelihood of such institutionalization. Winfield Decl., ¶¶ 18-20. Similarly, the incidence of injuries to consumers has also declined from 70 reports per thousand customers during the 2006-07 fiscal year to 66 for 2011-12. Id. at ¶¶ 24-25.

In sum, given the delay in filing the present lawsuit, Plaintiffs’ additional failure to show any real attempt to obtain available relief from the regional centers responsible for providing necessary supports and services, as well as data provided by Defendants suggesting that that the claimed detriment has not materialized, this Court finds irreparable harm prerequisite for injunctive relief has also not been established.

C. Balance of Hardships/Public Interest

While Plaintiffs offer the emotion-laden argument that protection of the developmentally disabled, as individuals constituting one of the most vulnerable portions of our society, far outweighs any budgetary concern on behalf of the state, as set forth above this Court has concluded that Plaintiffs have not demonstrated that Defendants did anything in contravention of the Medicaid Act that merits injunctive relief. Moreover, Plaintiffs’ showing of irreparable harm is sketchy at best. On the other hand, as Defendants point out, granting a preliminary injunction here would likely destabilize the entire disability service delivery system, in part because of the difficulty in immediately implementing new programs and provider payment structures, which the State estimates would take a minimum of three months to implement. Decl. of Barbara Golterman, ¶¶ 3-6. Budgetary shortfalls in DDS’ budget occasioned by granting the requested injunction could also disrupt the entire service delivery system. Decl. of Mark Hutchinson, ECF No. 78-1, ¶ 2. Consequently, the balance of hardships does not weigh in favor of Plaintiffs’ position either in the view of this Court.

CONCLUSION

Based on the foregoing, the Court finds that Plaintiffs have not demonstrated by clear and convincing evidence their entitlement to the extraordinary relief of a preliminary injunction in this matter. First and most importantly, they have failed to show a likelihood of success on the merits. Beyond that shortcoming, they have also not established the requisite irreparable harm and further have now shown that the *1125 balance of harms tips squarely in their favor. For all these reasons Plaintiffs’ Motion for Preliminary Injunction (ECF No. 83) is DENIED.

IT IS SO ORDERED.

. Unless otherwise noted, both ARC and CPA will be collectively referred throughout this Memorandum and Order as ''Plaintiffs.”

. The Managed Care decision was initially issued on December 13, 2012. Managed Pharmacy Care v. Sebelius, 705 F.3d 934 (9th Cir.2012). On May 24, 2013, after no rehearing en banc was requested, the initial decision was withdrawn and reissued without significant change at 716 F.3d 1235 .

. It should be noted that California claims there is no practical difference between HCBS waiver and Lanterman Act beneficiaries in the first place, because under the Lanterman Act, California guarantees the provision of community-based services to the disabled irrespective of whether the disabled consumer also happens to qualify under the federal HCBS waiver. As indicated above, California views the waiver program as a reimbursement program for services it is already obligated to provide. Because the two programs consequently conflate in this regard, the State contends that there is no divergent treatment between the two groups that could trigger protection under either the ADA or the Rehabilitation Act.

. The Court notes that both sides have submitted lengthy objections to certain evidence submitted both in support of and in opposition to this Motion, including the Declaration of Brian Winfield. To the extent this Memorandum and Order cites facts from the challenged evidence, those objections are overruled. Otherwise, because the evidence at issue was not germane to the Court’s decision herein, the Court need not specifically rule on the propriety of the remaining- objections and declines to do so.
