Preparing and Updating Your Clean Water Plans
An integrated approach to keep permits and prevention plans up to date.
Under the Clean Water Act (CWA), the U.S. Environmental Protection Agency (EPA) routinely works with federal and state regulatory agencies to ensure that facilities are compliant with clean water laws. These laws, which have been implemented to protect human and environmental health, require facilities to have plans in place for wastewater management and spill prevention.
TRC combines professional, technical and construction solutions to achieve your clean water goals. Our compliance experts review your current practices to ensure you meet EPA standards. We routinely prepare and update Spill Prevention Control and Countermeasure (SPCC) Plans and Stormwater Pollution Prevention Plans (SWPPPs) for midstream facilities. We also provide National Pollutant Discharge Elimination System (NPDES) Program permitting guidance to address the most significant issues involving pollutants in U.S. waters.
TRC’s Regulatory Expertise Puts You Ahead
TRC’s environmental and regulatory services encompass the full scope of water permitting and compliance in accordance with the Clean Water Act and similar guidelines at the federal, state and local levels. Our solutions include:.
- SPCC Plan preparation

Innovative Remedial Concepts to Address Microplastics
August 11, 2023
Microplastics (MP) encompass plastic particles ranging in size from 1 nanometer to 5 millimeters. MP historically appeared in lotions and creams as “microbeads,” which acted as exfoliants. MP also form through different processes including the gradual degradation of larger plastic items over time, which results in the generation of progressively smaller plastic particles. Additionally, textiles and synthetic clothing can form MP from daily wear and tear.
