Join SCS Engineers and John Tsun as he serves as one of the co-organizers for the 24th Annual Joint Venture NJDEP/Air & Waste Management Association (A&WMA) Regulatory Update Conference, November 21st.

This one-day virtual event provides attendees with the latest updates on New Jersey Department of Environmental Protection (NJDEP) regulatory initiatives and programs related to environmental compliance, air quality, contaminated site remediation and redevelopment, energy, materials sustainability, water quality, and climate change mitigation.

The conference offers a valuable opportunity for environmental professionals, regulators, and industry leaders to engage directly with NJDEP representatives and stay informed on emerging policies, research, and best practices shaping the future of sustainable environmental management.

On March 1, 2021, the New Jersey Department of Environmental Protection (NJDEP) proposed several amendments to air quality regulations pertaining to the regulation of New Jersey Hazardous Air Pollutants (NJHAPs) as well as fumigation operations.  The NJHAP regulations changes could significantly impact MSW landfills because they include proposed changes to hydrogen sulfide regulation as a NJHAP.

Key changes are summarized as follows:

• The NJDEP is proposing to regulate hydrogen sulfide as a NJHAP;
• Proposing a reporting threshold for H₂S of 90 lbs/yr,
• Proposing a State of the Art (SOTA) threshold for H₂S of 10,000 lbs/yr (5 tons/year).

Several potential implications could result from these proposed changes, including:

• Facilities with existing Title V Operating permits would be required to calculate the potential to emit (PTE) emissions of H₂S for existing sources. If H₂S emissions are above the very low reporting threshold of 90 lbs/yr, the H₂S PTE emission rate would need to be added to the Title V Operating permit during the next permit renewal or the next permit modification.
• Facilities subject to Emission Statement reporting and emitting H₂S in an amount greater than or equal to 90 lbs/yr would have to include H₂S emissions in their annual emissions statements.
• For sources with potential H₂S emissions of 90 lbs/yr or more, risk screening would be needed as part of (1) an initial operating permit for a new major facility or (2) for a minor or significant modification to an existing operating permit.
• For sources with potential H₂S emissions of 10,000 lbs/yr (5 tons per year) or more, a SOTA analysis would be required with certain permit applications. A SOTA analysis involves evaluating and potentially implementing available control technologies to reduce emissions and considers both technical feasibility and economic impact.  The proposed changes could lead to the need to implement additional landfill gas collection, control, and potentially treatment systems at some landfills.

A virtual public hearing regarding the proposed changes is scheduled for April 8, 2021, at 4:00 PM (ET).  A link to the virtual public hearing will be posted at http://www.state.nj.us/dep/aqm/curformp.html.

Written comments are due no later than April 30, 2021, to  www.nj.gov/dep/rules/comments.
