EPA’s Proposed Revisions Include the Incorporation of Fenceline Monitoring Provisions

The U.S. EPA’s recent proposed amendments to the NSPS and NESHAP regulations, set to be finalized on March 29, 2024, introduce provisions that broadly expand the NSPS and NESHAP regulations for the Synthetic Organic Chemical Manufacturing Industry and the Group I and II Polymers & Resins industries. A significant proposed amendment is the incorporation of fenceline monitoring provisions under HON regulations.

At Alliance, our technical teams are uniquely positioned to guide you through these new proposed fenceline monitoring provisions:

  1. Specialized Ambient Air Monitoring Staff: Alliance offers specialized staff with over 35 years of experience in air quality monitoring programs. Our team’s profound understanding of the technical, procedural, and regulatory intricacies of air quality monitoring, coupled with a robust track record, positions us uniquely to provide comprehensive guidance and adept solutions tailored to the new fenceline monitoring provisions.
  2. Experienced Environmental Consulting Staff: Alliance has conducted large-scale regulatory applicability determinations for the federal SOCMI rules, such as 40 CFR Part 60 Subpart VVa, 40 CFR Part 60 Subpart NNN, 40 CFR Part 60 Subpart RRR, and 40 CFR Part 63 Subparts F through H. Alliance additionally provides multiple clients with day-to-day compliance support with regards to the federal SOCMI rules.Alliance’s environmental consulting staff has been heavily involved with implementation programs associated with EPA’s risk and technology review (RTR) for the Refinery Sector, the MON RTR, and the EMACT RTR. This allows our team to provide valuable feedback on solutions and strategies that have been proven to be successful while minimizing exposure to the general public and Environmental Non-Governmental Organizations (NGOs).
  3. Pre-Compliance Monitoring Support: As currently proposed, fenceline monitoring must commence no later than 1 year after the final rule is promulgated. Alliance recommends pre-compliance monitoring to gain insights into your current emissions landscape and identify potential compliance hotspots. With the pre-compliance monitoring data, Alliance can readily help clients develop solutions for any identified concerns, such as the need for a site-specific monitoring plan.
  4. Digital Reporting Solutions: Streamline your compliance with our digital reporting solutions, designed to meet the enhanced reporting protocols.
  5. On-Demand Technical Support: Benefit from our national footprint of local offices with on-ground technical field support, leveraging the familiarity and expertise of our staff with local facilities to provide a smooth compliance transition.
