Air quality regulations are some of the most complex and challenging of all the environmental regulations that exist today. Since the passing of the Clean Air Act (CAA) Amendments of 1990, there has been an evolution of regulations aimed at reducing air pollutants (e.g., SO2, NOx, CO, VOC, PM, PM10, PM2.5, GHGs). Operators are often challenged in keeping up with the volume of evolving regulations at the federal, state, and local levels to institute best practices and remain in compliance. 

Since 1992, Trihydro's team of experts has assisted clients with CAA, state and local regulations, and industry challenges and growth. Our team can help implement regulatory strategies that fit your business. Whether you are looking for compliance evaluations and audits, regulatory analysis and applicability reviews, program implementation, training, permitting new projects, or due diligence reviews of potential acquisitions, our air team is ready to help meet those challenges.

 
Air Permitting

AIR PERMITTING

There are several programs under the CAA, and depending on the site, air permitting can be a relatively straightforward task, or it can be extremely complex and tedious. In addition to managing routine compliance with existing permits, operators should consider air permitting needs when building a new facility, modifying operations, renewing permits, or when regulations change. In general, a project or initiative cannot move forward without the proper air permits in place, and the time between submitting an air permit application and receiving a final permit can vary greatly. Therefore, air permitting is an important factor in executing projects and maintaining smooth operations.

Clean Air Compliance

CLEAN AIR ACT COMPLIANCE

Under the CAA, EPA has set emissions limits for a wide range of air pollutants from industrial sources in the United States. Maintaining compliance cost-effectively and efficiently requires evaluating how to best balance business objectives with regulatory requirements. Choosing the optimal path to regulatory compliance requires looking ahead to understand the long-term implications of various compliance options, considering both initial and future costs, and understanding the impact that future regulations may have.

Greenhouse Gas Management

GREENHOUSE GAS (GHG) MANAGEMENT

The Environmental Protection Agency (EPA) promulgated the first federal Greenhouse Gas (GHG) mandatory reporting rule (MMR) in 2009. Since then, state and local agencies have also promulgated or proposed mandatory GHG reporting requirements. Pursuant to Subpart A, facilities required to report GHG emissions must also retain an up-to-date written Greenhouse Gas Monitoring Plan (GMP). As part of maintaining a GMP, operators must collect relevant data through comprehensive field surveys and complete emissions calculations. Identifying potential data gaps and implementing a GHG data management plan are key steps in maintaining compliance with state and/or federal mandatory reporting rules.

Leak Detection
LEAK DETECTION AND REPAIR (LDAR)

LDAR has become an integral part of the day-to-day plant operations at petroleum refineries, chemical plants, natural gas plants, biodiesel plants, and ethanol facilities. Because of EPA’s enforcement initiatives, attention to fugitive emissions and maintenance of a fully compliant LDAR program is an operational focus.
