On September 16, 2022, the U.S. Court of Appeals for the Third Circuit affirmed a district court ruling that Pennsylvania state legislators and municipalities lacked standing to challenge the Delaware River Basin Commission’s (DRBC) regulation banning hydraulic fracturing for natural gas within the basin. Yaw v. DRBC, 49 F.4th 302 (3d Cir. 2022), aff’g No. 2:21-cv-00119, 2021 WL 2400765 (E.D. Pa. June 11, 2021); see Vol. XXXVIII, No. 3 (2021) of this Newsletter. The court held that the appellants failed to meet the standing requirements of Article III of the U.S. Constitution because: (1) in the case of the state senator appellants, individual members of the state legislature lack standing to assert the interests of the legislature as a whole; and (2) in the case of the municipality appellants, their alleged injuries were “conjectural” or “hypothetical,” as opposed to “actual” or “imminent.” The court also held that none of the appellants had standing as trustees of Pennsylvania’s public natural resources under the Environmental Rights Amendment to the Pennsylvania Constitution because the DRBC’s ban has not cognizably harmed the trust.

The five-member DRBC is governed by a compact between the federal government and four states that draw water from the Delaware River: Pennsylvania, New Jersey, Delaware, and New York, represented by a member of the U.S. Army Corps of Engineers and each state’s governor, respectively. See Delaware River Basin Compact, Pub. L. No. 87-328, 75 Stat. 688.

Pennsylvania – Mining

(By Joseph Reinhart, Sean McGovern, Gina Falaschi and Christina Puhnaty)

The Supreme Court of Pennsylvania has upheld a preliminary injunction of the Regional Greenhouse Gas Initiative (RGGI) rule granted by the Commonwealth Court of Pennsylvania. On July 8, 2022, the commonwealth court granted a preliminary injunction preventing the state from participating in RGGI pending resolution of the case. See Vol. 39, No. 3 (2022) of this Newsletter. Governor Tom Wolf appealed the injunction to the supreme court. On August 31, 2022, the supreme court denied the state’s emergency request to reinstate the automatic supersedeas, thereby maintaining the preliminary injunction while litigation on the merits proceeds before the commonwealth court later this year. See Ziadeh v. Pa. Legis. Reference Bureau, No. 79 MAP 2022 (Pa. Aug. 31, 2022).

As previously reported in Vol. 39, No. 2 (2022) of this Newsletter, the Pennsylvania Department of Environmental Protection’s (PADEP) CO2 Budget Trading Program rule, or RGGI rule, which links the state’s cap-and-trade program to RGGI, was published in the Pennsylvania Bulletin in April 2022. See 52 Pa. Bull. 2471 (Apr. 23, 2022). RGGI is the country’s first regional, market-based cap-and-trade program designed to reduce carbon dioxide (CO2) emissions from fossil fuel-fired electric power generators with a capacity of 25 megawatts or greater that send more than 10% of their annual gross generation to the electric grid.

On April 25, 2022, owners of coal-fired power plants and other stakeholders filed a petition for review and an application for special relief in the form of a temporary injunction, and a group of state lawmakers filed a challenge as well.

Pennsylvania – Mining

(By Joseph Reinhart, Sean McGovern, Gina Falaschi and Christina Puhnaty)

In late July 2022, the Pennsylvania Department of Environmental Protection (PADEP) published its Non-Regulatory Agenda, which outlines the agency’s upcoming plans related to its documents, manuals, and technical guidance. The Non-Regulatory Agenda outlines the agency’s intent to rescind its Engineering Manual for Mining Operations, TGD No. 563-0300-101 (Jan. 1, 1999), by the end of this year. The agenda also notes PADEP’s intent to revise several other technical guidance documents (TGDs) related to coal mining activities in the commonwealth. The TGDs identified by PADEP to be revised in early 2023 are:

  • Surface Water Protection – Underground Bituminous Coal Mining Operations, TGD No. 563-2000-655 (Oct. 8, 2005);
  • Financial Assurance and Bond Adjustments for Mine Sites with Post-Mining Discharges, TGD No. 563-2504-450 (Dec. 15, 2007) (draft);
  • Increased Operation and Maintenance Costs of Re-placement Water Supplies (on All Coal and Surface Noncoal Sites), TGD No. 562-4000-102 (Dec. 2, 2006);
  • Water Supply Replacement and Permitting, TGD No. 563-2112-605 (Dec. 31, 1998); and
  • Water Supply Replacement and Compliance, TGD No. 562-4000-101 (Oct. 18, 1999).

Draft revisions will be published in the Pennsylvania Bulletin and should be available online at https://www.depgreenport. state.pa.us/elibrary/GetFolder?FolderID=4556. The public will have an opportunity to comment on these draft revisions for a period of at least 30 days.

Rulemaking Review Committees Disapprove Proposed Water Quality Standard for Manganese

FNREL Mineral and Energy Law Newsletter

Pennsylvania – Mining

(By Joseph Reinhart, Sean McGovern, Gina Falaschi and Christina Puhnaty)

As reported in Vol. 55, No. 3 (2022) of the Water Law Newsletter, the Pennsylvania House and Senate Environmental Resources and Energy standing committees (Standing Committees) and the Independent Regulatory Review Commission (IRRC) recently disapproved a proposed rulemaking to change the water quality criterion for manganese in Pennsylvania. The future of the rulemaking is now uncertain.

Proposed Changes to Manganese Water Quality Criterion 

The proposed manganese rule would add a numeric water quality criterion for manganese of 0.3mg/L to Table 5 at 25 Pa. Code § 93.8c, which is intended to “protect human health from the neurotoxicological effects of manganese.” Executive Summary at 1, “Final-Form Rulemaking: Water Quality Standards and Implementation—Manganese” (Aug. 9, 2022). Section 93.8c establishes human health and aquatic life criteria for toxic substances, meaning the Pennsylvania Department of Environmental Protection (PADEP) would be regulating manganese as a toxic substance. The existing criterion of 1.0 mg/L, which was established in 25 Pa. Code § 93.7 as a water quality criterion, would be deleted. The 0.3 mg/L criterion would apply to all surface waters in the commonwealth. PADEP identified the parties affected by the manganese rule to be “[a]ll persons, groups, or entities with proposed or existing point source discharges of manganese into surface waters of the Commonwealth.” Executive Summary at 3.

PADEP also specifically identified “[p]ersons who discharge wastewater containing manganese from mining activities” as affected parties, and expects that mining operators would need to perform additional treatment to meet this criterion.

PADEP’s RACT III Rule Requires Action from Major Sources of NOx and VOCs by End of Year

FNREL Mineral and Energy Law Newsletter

Pennsylvania – Mining

(By Joseph Reinhart, Sean McGovern, Gina Falaschi and Christina Puhnaty)

On November 12, 2022, the Pennsylvania Environmental Quality Board (EQB) published amendments to the Pennsylvania Department of Environmental Protection’s (PADEP) regulations in 25 Pa. Code chs. 121 and 129 for all major stationary sources of nitrogen oxides (NOx) or volatile organic compound (VOC) emissions, which is commonly known as the RACT III rule. See 52 Pa. Bull. 6960 (Nov. 12, 2022). The rule requires major sources of either or both of these air pollutants in existence on or before August 3, 2018, to meet reasonably available control technology (RACT) emission limits and requirements by January 1, 2023. See also Vol. 39, No. 1 (2022) of this Newsletter (Pennsylvania – Oil & Gas report).

These regulations are being promulgated to address federal Clean Air Act (CAA) RACT requirements to meet the 2015 ozone National Ambient Air Quality Standards (NAAQS) in the commonwealth. The CAA requires a reevaluation of RACT when new ozone NAAQS are promulgated. RACT is required in nonattainment areas, including the Ozone Transport Region, which includes Pennsylvania. The RACT III rulemaking establishes presumptive RACT requirements and emission limits for specific source categories of affected facilities. The RACT III rulemaking also imposes additional requirements for all major sources of NOx and/or VOCs, not just those subject to the presumptive RACT requirements and limitations.

RACT III applies to all major sources of VOCs and NOx. Because the commonwealth is in the Northeast Ozone Transport Region, the major source threshold is 50 tons per year (tpy) of VOCs and 100 tpy of NOx.

Id. Final amendments to treatment systems would be implemented through PADEP’s permitting process and other approval actions. Consulting and engineering firm Tetra Tech estimated the overall cost to the mining industry to achieve compliance with the 0.3 mg/L criterion “could range between $44–$88 million in annual costs (that is, for active treatment systems using chemical addition for manganese removal) and upwards of $200 million in capital costs.” Comment and Response Document at 213, “Water Quality Standard for Manganese and Implementation” (Aug.

SEC’s Proposed ESG rule – Key Takeaways for Public and Private Companies

Pittsburgh Business Times

In March, the Securities and Exchange Commission (SEC) released a proposed rule entitled Enhancement and Standardization of Climate-Related Disclosures for Investors. If finalized, this rule would become some of the first mandatory Environmental, Social and Governance (ESG) reporting requirements for U.S. companies, requiring the disclosure of climate-related risk information in registration statements and periodic reports.

This proposed regulation has significant consequences not just for public companies, but private companies as well. Babst Calland Environmental Attorney Gina N. Falaschi explains the implications of the proposed rules, should they take effect.

What requirements could the rules introduce?

Under the SEC proposal, public companies would be required to disclose the oversight and governance of climate-related risk by their board and management; how any climate-related risk has a material effect on business and consolidated financial statements; the process for identifying, assessing and managing climate-related risks and how to integrate those processes into the company’s overall risk management; whether the company has adopted a transition plan to deal with climate-related risks and how to measure any physical or transitional risks to its operations; the effect of severe weather events and related natural conditions; and information regarding any publicly set climate-related targets or goals.

The SEC’s proposal also requires the disclosure of certain greenhouse gas emissions. These emissions are divided into three categories based on the Greenhouse Gas Protocol definitions. Scope 1 emissions are the direct greenhouse gas emissions that occur from sources that a company owns or controls, such as emissions from manufacturing activities and vehicles. Scope 2 emissions are the indirect greenhouse gas emissions that occur from the generation of energy that a company buys and consumes in its operations. Scope 3 emissions are the result of assets not owned or controlled by a company that the company indirectly impacts in its value chain, both upstream and downstream, from the company’s operations, such as the purchased goods and services, waste generation, business travel, downstream transportation, distribution and use of products sold, and the end-of-life treatment of products sold.

In March, the Securities and Exchange Commission (SEC) released a proposed rule entitled Enhancement and Standardization of Climate-Related Disclosures for Investors. If finalized, this rule would become some of the first mandatory Environmental, Social and Governance (ESG) reporting requirements for U.S. companies, requiring the disclosure of climate-related risk information in registration statements and periodic reports.

This proposed regulation has significant consequences not just for public companies, but private companies as well.

Smart Business spoke with Gina N. Falaschi, an associate at Babst Calland, about the implications of the proposed rule, should it take effect.

What requirements could the rule introduce?

Under the SEC proposal, public companies would be required to make a number of disclosures related to their climate-related risks and impact. Those include disclosures regarding the oversight and governance of climate-related risk by their board and management, how any climate-related risk has a material effect on business and consolidated financial statements, and information regarding any publicly set climate-related targets or goals.

The SEC’s proposal also requires the disclosure of certain greenhouse gas emissions, which are divided into three categories. Scope 1 emissions are the direct greenhouse gas emissions that occur from sources that a company owns or controls. Scope 2 emissions are the indirect greenhouse gas emissions that occur from the generation of energy that a company buys and consumes in its operations. Scope 3 emissions are the result of assets not owned or controlled by a company that the company indirectly impacts in its value chain, both upstream and downstream from the company’s operations. Scope 3 emissions would have to be disclosed only if considered ‘material.’

Governor Wolf Signs Act 151 Addressing Data Breaches Within Local Entities

Public Sector Alert

(by Michael Korns and Ember Holmes)

On Thursday, November 3, 2022, Governor Tom Wolf signed PA Senate Bill 696, also known as Act 151 of 2022 or the Breach of Personal Information Notification Act.  Act 151 amends Pennsylvania’s existing Breach of Personal Information Notification Act, strengthening protections for consumers, and imposing stricter requirements for state agencies, state agency contractors, political subdivisions, and certain individuals or businesses doing business in the Commonwealth.  Act 151 expands the definition of “personal information,” and requires Commonwealth entities to implement specific notification procedures in the event that a Commonwealth resident’s unencrypted and unredacted personal information has been, or is reasonably believed to have been, accessed and acquired by an unauthorized person.  The requirements for state-level and local entities differ slightly; this Alert will address the impact of Act 151 on local entities.  While this law does not take effect until May 22, 2023, it is critical that all entities impacted by this law be aware of these changes.

For the purposes of Act 151, the term “local entities” includes municipalities, counties, and public schools.  The term “public school” encompasses all school districts, charter schools, intermediate units, cyber charter schools, and area career and technical schools.  Act 151 requires that, in the event of a security breach of the system used by a local entity to maintain, store, or manage computerized data that includes personal information, the local entity must notify affected individuals within seven business days of the determination of the breach.  In addition, local entities must notify the local district attorney of the breach within three business days.

The definition of “personal information” has been updated, and includes a combination of (1) an individual’s first name or first initial and last name, and (2) one or more of the following items, if unencrypted and unredacted:

A Few Certain Things – Taxes, Hydrogen, Natural Gas, and Climate Change?

The American College of Environmental Lawyers (ACOEL)

(By Donald C. Bluedorn II)

On November 3, 2022, Pennsylvania Governor Wolf signed House Bill 1059, which amends the Commonwealth’s Tax Reform Code and, among other things, establishes the Pennsylvania Economic Development for a Growing Economy (“PA EDGE”) program, consisting of tax credits for four economic areas.  https://www.legis.state.pa.us/cfdocs/billinfo/billinfo.cfm?sYear=2021&sInd=0&body=H&type=B&bn=1059.

Much of the publicity around the bill has focused on the tax credits available to promote a “hydrogen hub” and the use of hydrogen-based technologies.  Indeed, the bill provides for tax credits up to $50 million per year, or a total of $1 billion over a 20-year period.

In explaining his support for House Bill 1059, Governor Wolf started by noting his belief in the importance of the role of hydrogen in addressing the effects of climate change.  “In its most recent report, the Intergovernmental Panel on Climate Change notes that ‘hydrogen is a promising energy carrier for a decarbonized world,’ and highlights hydrogen’s potential to ‘provide low-carbon heat for industrial processes or be utilized for direct reduction of iron ore.’”  https://www.governor.pa.gov/wp-content/uploads/2022/11/20221103-1059.pdf.

The Governor then went on to note his belief that the use of hydrogen must be tied responsibly to the reduction of emissions and the consideration of Environmental Justice.

That said, I recognize that in order for hydrogen to play a meaningful role in reducing emissions, we must ensure that hydrogen used is truly “clean” through stringent emissions standards. We must also commit to strong and equitable community protections to prevent impacts to already overburdened communities and to guide benefits to communities that need them.

Perhaps the most controversial provisions of the bill, or at least those that drew the most attention in much of the press, were the provisions that also authorized a tax credit for the use of natural gas in the manufacturing of petrochemicals or fertilizers.

EPA Doubles Down in Long-Awaited Supplemental Proposed Oil and Gas Methane Rule

Energy Alert

(by Gary Steinbauer, Gina Falaschi and Christina Puhnaty)

On November 11, 2022, the U.S. Environmental Protection Agency (EPA) released a pre-publication version of its supplemental proposal for Standards of Performance for New, Reconstructed, and Modified Sources and Emissions Guidelines for Existing Sources: Oil and Natural Gas Sector Climate Review (Supplemental Proposal).  The Supplemental Proposal has been highly anticipated since EPA published its initial proposal on November 15, 2021.  EPA, Standards of Performance for New, Reconstructed, and Modified Sources and Emissions Guidelines for Existing Sources: Oil and Natural Gas Sector Climate Review, 86 Fed. Reg. 63110 (Nov. 15, 2021) (Initial Proposal).

EPA currently regulates emissions from oil and natural gas facilities under 40 C.F.R Part 60 Subparts OOOO[1] and OOOOa.[2]  As part of the Initial and Supplemental Proposals, EPA would regulate oil and natural gas facilities constructed, modified, or reconstructed after November 15, 2021, under a new Subpart OOOOb.  With the Supplemental Proposal, EPA has released proposed regulatory language for Subpart OOOOb.  In addition, EPA released proposed regulatory text for emissions guidelines in a new Subpart OOOOc.  These emissions guidelines are intended to inform states in the development, submittal, and implementation of state plans to establish standards of performance for greenhouse gases (in the form of limitations on methane) from sources existing on or before November 15, 2021.  Under the Supplemental Proposal, states and tribes would be required to submit plans to EPA for review within 18 months of the publication of a final rule, with a compliance deadline for existing sources that is no later than 36 months after the deadline to submit the plan to EPA.

Out of Sight, Out of Mind: The Remote Worker and the FMLA’s 50/75 Rule

Legal Intelligencer

(by Alex Farone and Janet Meub)

Navigating the Family and Medical Leave Act (FMLA) in the COVID era, including the pandemic-related amendments, has felt like a minefield for many employers. Now that the surge of COVID-related uses of FMLA leave has largely passed, a new aspect of statutory compliance is emerging as a hot-button issue: treatment of remote workers under the FMLA.

The FMLA provides eligible employees with up to 12 weeks of protected, unpaid leave per year for qualifying family or medical reasons. In order to be eligible for FMLA coverage, four elements must be met:

  1. The employer is a covered employer under the Act, meaning it has at least 50 employees for at least 20 weeks in the current or previous year;
  2. The employee must have worked for the employer for at least 12 months, not necessarily consecutively;
  3. The employee must have worked at least 1250 hours in the last 12-month period; and
  4. The employee must be employed at a worksite where the employer employs at least 50 employees within a 75-mile radius.

Many employers do not pay much consideration to the last element, also known as the “50/75 Rule,” likely because the first element requires 50 employees and in the majority of instances those 50 employees are by default going to work within a 75-mile of the employer’s office. However, in the COVID era and beyond, more and more employees are permitted to work remotely on a full-time basis, and employers are hiring remote employees all over the country, regardless of the location of the employer’s physical office or operations.

The FMLA itself does not address remote workers, but the Department of Labor’s regulations specify that an employee’s personal residence is not a worksite for employees who work at home by telecommuting.

Pennsylvania Establishes New Tax Credits to Support Regional Hydrogen Hub Opportunities

Infrastructure Alert

(by Jim Curry, Sean McGovern and Lee Banse)

On November 3, 2022, Pennsylvania Governor Tom Wolf approved legislation that will provide up to $50 million of annual tax credits for facilities located in a Pennsylvania regional clean hydrogen hub that use clean hydrogen produced at the hub in manufacturing.[1]  The tax credits are available between January 1, 2024 until December 31, 2043, providing up to $1 billion of credits over the life of the program.[2]

The Pennsylvania tax credits complement federal efforts to foster a clean hydrogen industry through the development of regional clean hydrogen hubs. The federal Bipartisan Infrastructure Law, enacted in November 2021, provided $7 billion for the Department of Energy (DOE) to establish between six to ten regional clean hydrogen hubs for the development of a domestic clean hydrogen industry.[3]

Under the new Pennsylvania program, the credits are available to taxpayers who have made a capital investment of at least $500 million to construct a facility in a Pennsylvania regional clean hydrogen hub, have satisfied certain job creation and employment requirements, and who purchase clean hydrogen produced in the Pennsylvania hub for use in manufacturing at the facility.[4]  The tax credits will be applied at a rate of 81 cents per kilogram of clean hydrogen purchased.[5]  Qualifying taxpayers may also apply for a tax credit of 47 cents per thousand cubic feet of natural gas purchased for use at the manufacturing facility.[6]  A qualified taxpayer may assign the tax credits, subject to certain requirements in the statute.[7]

In a press release on the bill, Governor Wolf stressed the role clean hydrogen will play in reducing carbon emissions, and his support for applications for a regional clean hydrogen hub in Pennsylvania.

Yaw Bill Ensuring Royalty Transparency for Leaseholders Signed by Governor

PIOGA Press

Sources for below article: Pennsylvania Oil & Gas Landowner Alliance (POGLA) Post – November 6, 2022, Senator Yaw Press Release dated 11/7/22, and ‘Pennsylvania General Assembly Enacts Senate Bill to Amend Oil and Gas Lease Act’ alert by Babst Calland published on 11.8.22

(By Chelsea Heinz and Devlin Carey)

Legislation aimed at ensuring landowners are afforded a clear and distinct assessment of royalties paid to them through lease agreements with oil and natural gas operators has been signed by Governor Tom Wolf.

On November 3, 2022, the Pennsylvania General Assembly enacted Senate Bill 806, which amends the Oil and Gas Lease Act of 1979 (P.L. 183, No. 60). The new act seeks to increase transparency around the payment of royalties from oil and natural gas operators to landowners pursuant to their lease agreements.

Senator Gene Yaw (R-23) believes the act will address recent concerns among landowners regarding the way in which royalties are being calculated, described and ultimately paid.

“Concerns have been expressed by land and mineral owners for some time now centered on the lack of transparency that can come with deductions from their royalty payments,” Yaw said. “In some cases, general deductions with little to no description are subtracted from landowner’s checks, leaving them with a fraction of what was promised. “My legislation would not impact lease agreements, but it would require entities making payments to landowners to provide more description, clarity and uniformity on their royalty check statements, something I’ve heard a great deal about from leaseholders across our region,” Yaw said. “This proposal is designed to help ensure all parties feel their lease agreements are executed as intended, and it will help mitigate concerns that have developed in recent years.”

Senate Bill 806, now Act 153 of 2022, was supported by various agencies and organizations, including the Pennsylvania Farm Bureau, the Pennsylvania Oil and Gas Landowner Alliance, the Marcellus Shale Coalition, Bounty Minerals, the Pennsylvania Independent Oil &

EPA Publishes Proposed Rule Requiring All Major Stationary Sources to Account for Fugitive Emissions in NSR Permitting

PIOGA Press

(By Gary Steinbauer, Gina Falaschi and Christina Puhnaty)

On October 14, 2022, the U.S. Environmental Protection Agency published a proposed rule that would require all emission sources subject to the Agency’s major New Source Review (NSR) permitting program to consider fugitive emissions when evaluating whether a new source or physical or operational change triggers the stringent major NSR permitting requirements. 87 Fed. Reg. 62,322 (Oct. 14, 2022) (Proposed Rule). The treatment of fugitive emissions, i.e., those “which could not reasonably pass through a stack, chimney, vent, or other functionally equivalent opening,” under the major NSR permitting program has been controversial for decades. While EPA predicts that the Proposed Rule will have limited impact on the regulatory community, EPA and state air permitting authorities may now place even greater pressure on industry to predict and quantify “fugitive emissions” from physical or operational changes to their facilities.

The major NSR permitting program is the Clean Air Act’s permit program that applies to the construction of new “major sources” and “major modifications” (i.e., qualifying physical or operational changes) to existing “major sources.” Applicability determinations under the major NSR program often rely heavily on predicted emissions from a new source or planned physical or operational changes to an existing source. When the new or existing source is located in an area that is in attainment with the Clean Air Act’s national ambient air quality standards (NAAQS), the major NSR program’s Prevention of Significant Deterioration (PSD) requirements apply. More stringent requirements, known as non-attainment NSR requirements, apply when the source will be or is located in an area that is not meeting one or more of the NAAQS.
