Recent Changes — Environment & Natural Resources
Twelve material changes have reshaped the federal-state-local environmental architecture across 2023-2026. The verification cycle's aggregate finding — substantive federal-floor architecture continuing at most regulatory layers AND federal/state/local divergence operating at varying intensity across the six sub-domains with MC32 PRIMARY Both/And at SD5 (federal/state EJ divergence) and D6-Q2 PRIMARY HOM at SD4 (anchor environmental-compliance commitment-vs-actual; 6th project-wide) — is composed of these events. The most consequential structural rollback is the GHG endangerment-finding rescission of February 18, 2026 plus the federal EJ EO chain revocation of January 20-21, 2025. The most consequential single positive PA-3-specific event is the SDP AHERA DOJ Deferred Prosecution Agreement of June 26, 2025 — the first U.S. school district criminally charged under AHERA — and the SDP environmental management budget response that tripled spending plus Penn's $100M contribution. The most consequential PA state expansion is the PA DEP Final EJ Policy effective January 3, 2026 — the first update in over 20 years — plus PennEnviroScreen, the OEJ at Special Deputy Secretary level, and the $267,825,172 RISE PA industrial decarbonization grants. The most consequential federal-policy-cycle convergence is at SD5 where federal EJ dismantlement and PA state EJ expansion operate simultaneously through 2025-2026 under MC32 architectural Both/And.
Sackett v. EPA narrows WOTUS scope under Clean Water Act § 404
The U.S. Supreme Court in Sackett v. EPA, 598 U.S. 651 (2023), narrowed the definition of "waters of the United States" under [CWA](/paul/campaign/empower/glossary/#cwa) § 404, reducing [USACE](/paul/campaign/empower/glossary/#usace) wetlands jurisdiction to wetlands with a continuous surface connection to navigable waters. Isolated wetlands — including some urban marsh complexes — may be outside CWA § 404 jurisdiction under the post-Sackett standard. The practical effect on John Heinz NWR's Tinicum Marsh depends on whether the Marsh's hydrological connection to the Delaware River system meets the Sackett standard; USACE jurisdictional determination requires institutional retrieval.

IRA Superfund excise tax restoration
The Inflation Reduction Act of 2022 reinstated the federal Superfund excise tax on chemicals and petroleum products (originally enacted 1980; expired 1995; reinstated effective January 1, 2023 at the original rates, updated for inflation). The excise tax supplements the Superfund trust fund used to finance federal-lead [CERCLA](/paul/campaign/empower/glossary/#cercla) remediation at [NPL](/paul/campaign/empower/glossary/#npl) sites where responsible parties cannot be identified or compelled to pay. The tax collection operates independently of EPA enforcement priorities — statutorily anchored and administered through established IRS tax machinery.

LCRI finalized; EPA defending in AWWA v. EPA
The EPA Lead and Copper Rule Improvements (LCRI) was finalized October 8, 2024 (89 FR 86418). Compliance date November 1, 2027 (baseline inventory plus service line replacement plan due). Mandatory full LSL replacement by November 1, 2037; action level reduced to 10 ppb; replacement plans must include prioritization strategy for schools, childcare facilities, and low-income neighborhoods; property-owner consent required for full-property-side replacement; post-replacement filters provided for up to six months. EPA filed Respondents' Brief defending the rule in AWWA v. EPA (D.C. Circuit, February 20, 2026), arguing it "is lawful, reasonable, and should be upheld." No reconsideration or non-enforcement guidance initiated; oral argument before D.C. Circuit likely later in 2026. EPA delayed releasing FY 2025 [LSL](/paul/campaign/empower/glossary/#lsl) replacement [SRF](/paul/campaign/empower/glossary/#srf) allocations (as of November 2025), creating a capital-flow uncertainty dimension.

Trump EOs 14148 / 14151 / 14173 revoke historical federal EJ EO chain
Three Trump executive orders within 24 hours of taking office revoked the historical federal EJ executive order chain. EO 14148 ("Unleashing American Energy," January 20, 2025); EO 14151 ("Ending Radical And Wasteful Government DEI Programs And Preferencing," January 20, 2025); EO 14173 ("Ending Illegal Discrimination And Restoring Merit-Based Opportunity," January 21, 2025). Collectively revoked EO 12898 (Clinton, 1994, "Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations") and related EOs and guidance — the foundation of three decades of federal [EJ](/paul/campaign/empower/glossary/#ej) policy. EPA March 12, 2025 implementation order followed. The federal EJ infrastructure that existed before January 2025 is not merely reduced; it is in substantial functional collapse at the administrative-program level.

EO 14260 "Protecting American Energy From State Overreach"
EO 14260 directs the Attorney General to identify and take "all appropriate action to stop enforcement" of state laws addressing "climate change," "environmental justice," or [GHG](/paul/campaign/empower/glossary/#ghg) emissions that burden energy development. K&L Gates legal analysis (January 8, 2026) specifically flagged EO 14260 as a potential legal threat to the [PA DEP](/paul/campaign/empower/glossary/#dep-pa) Final EJ Policy adopted January 3, 2026. As of May 2026, no specific DOJ action against PA DEP's EJ Policy or associated permit requirements has been identified. The mechanism is in place through EO 14260; the specific PA challenge has not yet been filed. EO 14260 confirms a federal executive mechanism directing the AG to identify and challenge state EJ policies — even absent specific PA action, the mechanism exists and compounds the D6-Q1 PA state EJ durability question.

SDP AHERA DOJ Deferred Prosecution Agreement — first U.S. school district criminally charged under AHERA
DOJ filed the Deferred Prosecution Agreement on June 26, 2025 (U.S. Attorney for the Eastern District of PA; DOJ Environmental Crimes Section; EPA Criminal Investigation Division). The [School District of Philadelphia](/paul/campaign/empower/glossary/#sdp) is the first school district in U.S. history criminally charged under [AHERA](/paul/campaign/empower/glossary/#ahera); first use of DPA against a public school district in an AHERA case. 8 criminal counts: 7 failures to conduct triennial inspections at named schools (S. Weir Mitchell Elementary, Charles W. Henry Elementary, and five others); 1 failure to conduct six-month inspection at Building 21 Alternative HS. DPA cites 31 buildings with asbestos problems 2015-2023; asbestos "improperly addressed [by using] duct tape to cover it up" per U.S. Attorney Metcalf press release. 5-year judicial monitoring; criminal charges dropped if SDP meets compliance for 5 years. SDP annual environmental management budget: $10.2M FY 2021 → $55.7M FY 2025 (tripled); staff 21 → 39; all 300+ buildings now inspected twice/year. Penn contributed $100M to SDP environmental management (same year probe began). Frankford High closed for $20M asbestos remediation (as of January 2026).

EPA Office of Research and Development formally eliminated; OASES created at ~500 of 1,540 positions
EPA announced [ORD](/paul/campaign/empower/glossary/#ord) elimination July 18, 2025; OASES (Office of Applied Science and Environmental Solutions) created September 22, 2025 (Administrator Zeldin memo). ORD had 1,540 staff; OASES holds approximately 500 positions per EPA spokesperson (Federal News Network, May 8, 2026) and E&E News (April 2026). Earlier C&EN reporting (May 2025, before OASES formally opened) gave ~300. EPA total staffing reduced to 12,448 (-3,700, -23% from January 2025). Per AFGE Council 238 president: "independent arm of research…effectively completely dismantled; peer-reviewed publications through that arm…completely gone." Future [NAAQS](/paul/campaign/empower/glossary/#naaqs) reviews including the scheduled PM2.5 and ozone reviews will be conducted by a successor office with approximately one-third of ORD's former capacity. EPA reduced headcount by approximately 3,000 between FY 2025 and FY 2026.

~50 EJ-focused EPA staff terminated; EJScreen offline; ~$20B IRA grants cancelled
Approximately 50 EJ-focused EPA staff terminated August 2025. [EJScreen](/paul/campaign/empower/glossary/#ejscreen) mapping tool taken offline. EPA EJ collaborative problem-solving grant program paused or cancelled. Approximately $20 billion [IRA](/paul/campaign/empower/glossary/#ira) grants cancelled affecting environmental justice community investments including Brownfields and climate resilience. EPA EJ office substantially reduced. EPA Region 3 (Philadelphia) continues to operate its NPDES and CERCLA programs but without the EJ-specific overlay that was operative prior to January 2025. Carry-forward from D2 MC-V-5 (verified 2026-05-02).

PA DEP Final Environmental Justice Policy effective — first update in 20+ years
PA DEP Final EJ Policy effective January 3, 2026 (DEP Doc. 015-0501-002; 56 Pa. Bull. 81); first update since 2004; retains core structure of September 2023 interim final policy with refinements. PennEnviroScreen mapping tool (32 environmental, health, and socioeconomic indicators; expanded EJ Area criteria including ≥80th percentile score and highest-5% Pollution Burden Score census block groups). OEJ at Special Deputy Secretary level under Fernando Treviño. Enhanced public participation in EJ Areas for major permit decisions. PA DEP enforcement prioritization in EJ Areas. Separate EJ-specific investments (PA DEP Final EJ Policy; OEJ infrastructure; $600K community organization EJ outreach grants) continue on parallel track from RISE PA. PA does not have a freestanding EJ statute — the Policy operates as administrative guidance, not codified law, making it subject to revision by PA DEP under any future administration without legislative action (the D6-Q1 administrative-vulnerability question).

EPA GHG Endangerment-Finding Rescission — Final Rule (91 FR)
EPA published the final rescission of the 2009 Endangerment Finding on February 18, 2026 (91 FR; Docket EPA-HQ-OAR-2025-0194); effective April 20, 2026. GHG vehicle standards promulgated since 2009 are repealed. Criteria pollutant and [HAP](/paul/campaign/empower/glossary/#hap) standards for vehicles are retained. Five distinct D.C. Circuit petitions for review pending: (1) coalition of 17 health/environmental organizations February 18, 2026 (Earthjustice, EDF, NRDC, Lung Association); (2) 18 young people represented by Our Children's Trust February 18, 2026; (3) Zero Emission Transportation Association (EV trade) February 20, 2026; (4) Massachusetts v. U.S. EPA, No. 26-1061 (D.C. Cir.) by 24 states plus 15 local governments March 19, 2026, led by NY / MA / CA / CT AGs with PA Governor Shapiro among signatories; (5) April 2026 administrative reconsideration petitions arguing the final rule was not the "logical outgrowth" of the proposed rule. 25-state intervenor coalition led by WV and KY filed March 6, 2026 to defend the rescission. The contestation is bidirectional: 24 states petition for review; 25 states intervene to defend. No stay granted as of verification date.

$267,825,172 RISE PA industrial decarbonization grants announced
The Governor Shapiro administration announced $267,825,172 in RISE PA (Reducing Industrial Sector Emissions in Pennsylvania) industrial decarbonization grants on April 28, 2026 — a $396 million statewide industrial decarbonization grant program funded through EPA's Climate Pollution Reduction Grants (IRA-funded). 31 manufacturing projects in 23 Pennsylvania counties; projects reduce GHG emissions and lower energy costs; estimated 1.3 million metric tons CO₂e reduction in first year; $3.1 million in annual energy cost savings. Not primarily an EJ grant program — EJ area prioritization is one program criterion, not the program's framing. RISE PA is at least as significant as evidence of Shapiro administration drawing down IRA-funded climate grants proactively at a moment when the federal layer is rolling back those same IRA programs — supporting the MC32 Both/And documentation. PA DEP administers.

Philadelphia County NPL site count: 3 active sites confirmed
Phase 3 verification confirms: 3 active NPL sites in Philadelphia County (per Homefacts.com aggregation of EPA Superfund data, corroborated by EPA Superfund sites in reuse PA documentation). Named PA-3-proximate NPL sites: Enterprise Avenue NPL site (North Philadelphia industrial legacy); Metal Bank Superfund site (Philadelphia, Schuylkill River corridor); Lower Darby Creek Area (Philadelphia County plus Delaware County, Southwest PA-3 boundary at Eastwick). The substructure baseline figure of "approximately 44 Superfund-designated sites" — which the Phase 1 draft carried forward — likely reflects a broader CERCLA-addressed site inventory (CERCLIS sites below NPL threshold; HSCA-addressed sites; brownfields with CERCLA contamination history) rather than the current NPL roster specifically. The Encyclopedia of Greater Philadelphia's characterization that Greater Philadelphia historically held "some of the nation's highest concentrations of environmentally hazardous Superfund sites" applies to the broader metropolitan region rather than to the current active NPL count for Philadelphia County specifically. Analytical consequence: the five-mechanism brownfield gap analysis at [G6-SD3-01](https://github.com/square-party/square-party-site/blob/main/reference-info/verified-pa3-domain-content/D6-environment/D6_envNatRes_verified_2026-05-11.md#g6-sd3-01) does not depend on NPL count.

What's not on this list
Several items the verification cycle examined did not produce a material change within the verified window and so do not appear above. The Clean Air Act statutory architecture (42 U.S.C. § 7401 et seq.) is unchanged; criteria-pollutant NAAQS continue to operate under PA APCA / PAMS delegated authority. The Safe Drinking Water Act statutory architecture (42 U.S.C. § 300f et seq.) is unchanged; LCRR/LCRI mandatory replacement framework is operative per MC-06. CERCLA, SARA, RCRA Subtitle C, the 2002 Brownfields Law, TSCA Title II and Title IV, AHERA, Title X HCDA, ESA, MBTA, CWA § 404, and NEPA are all statutorily stable. The PA Air Pollution Control Act (35 P.S. § 4001 et seq.), PA Clean Streams Law (35 P.S. § 691.1 et seq.), PA SDWA (35 P.S. § 721.1 et seq.), PA Act 2 of 1995 (35 P.S. § 6026.101 et seq.), PA HSCA (35 P.S. § 6020.101 et seq.), and PA Lead Paint Abatement Act (35 P.S. § 5901 et seq.) are unchanged. The Philadelphia Code Title 3 (Air Management Services), Title 6 (Health, including the Philadelphia Lead Disclosure Law at Chapter 6-800), and Title 15 (Parks and Recreation) are unchanged. The IRA-restored Superfund excise tax (effective January 1, 2023) continues operative independent of EPA enforcement priorities. PA DEP Bureau of Safe Drinking Water primacy is unchanged. USFWS administration of John Heinz NWR / Tinicum Marsh as America's First Urban Wildlife Refuge (1972) is unchanged. The 30-year history of EO 12898 prior to revocation, however, is no longer the operative federal EJ architecture — that change is documented above under the January 2025 EO chain entry.
Reading these together
The cumulative pattern across these twelve entries is federal architecture erosion at varying intensity across the six sub-domains plus PA state and Philadelphia local architecture continuing or expanding. Federal architecture erosion runs through the GHG endangerment-finding rescission (most dramatic at SD1; G6-SD1-01 principal anchor), the EPA ORD elimination (affecting future NAAQS scientific capacity at SD1), the federal EJ EO chain revocation and the August 2025 ~50 EJ-staff terminations plus ~$20B IRA grant cancellations and EJScreen offline (most dramatic at SD5; G6-SD5-01 principal anchor), the federal OECA enforcement-emphasis changes (affecting SD1, SD2, SD3 enforcement backstop), and EO 14260 as a federal mechanism in place directing AG challenge to state climate / EJ laws (operative but no specific PA action as of May 2026). PA state continuation runs through the PA DEP Final EJ Policy effective January 3, 2026 (first update in 20+ years; PennEnviroScreen; OEJ Special Deputy Secretary), the LCRI operative under PA DEP BSDW primacy with EPA defending in AWWA v. EPA, PA Act 2 / HSCA voluntary cleanup, and PA DCNR conservation architecture. Philadelphia local continuation runs through PAMS delegated CAA authority, PWD's 2026 LSL pilot and Green City Clean Waters CSO consent order exceeding its 10-year reduction goal, PPR park system, and the SDP's tripled environmental management budget and 5-year judicial monitoring response to the AHERA DPA. Federal-rep leverage operates at every layer — D.C. Circuit endangerment-finding rescission litigation; LCRI defense in AWWA v. EPA; EPA OECA enforcement priority; SAMHSA-equivalent ORD scientific capacity; PA EJ Policy durability via D6-Q1; the EO 14260 trajectory; and CERCLA / NPL appropriation. The MC32 PRIMARY Both/And at SD5 and the D6-Q2 PRIMARY HOM at SD4 (6th commitment-vs-outcome HOM project-wide) hold the disciplinary structure for analyzing this convergence without premature analytical closure.
