About the facility

The Aquatic manufacturing facility is located at 801 Northern Pacific Road SE, Yelm, Washington, and has operated at this location since 1981. Aquatic manufacturers bathtubs, showers, spas and other fiberglass reinforced plastic products.

What air pollutants are emitted from Aquatic?

Aquatic is a major source for the compound Styrene, which is both a Hazardous Air Pollutant (HAP) under federal air regulations and a Toxic Air Pollutant (TAP) under Washington’s regulations. Other air pollutants emitted by Aquatic include the compounds Methyl Methacrylate (MMA) and Diphenylmethane diisocyanate (MDI), which are both HAPs and TAPs, and particulate dust. Aquatic also emits criteria air pollutants from the combustion of natural gas.

¿Aumentarán las emisiones de contaminantes atmosféricos como consecuencia de la aprobación de este POA?

No. Los AOP toman los límites de emisiones atmosféricas preexistentes y otros requisitos relacionados con el aire de múltiples orígenes, como normativas estatales, normativas federales y aprobaciones de permisos de construcción, y los organizan en un único permiso. Los POA también deben establecer suficientes requisitos de control, registro e información para garantizar el cumplimiento continuo de los límites y requisitos aplicables.

How does Aquatic assure compliance?

Aquatic implements pollution prevention measures to prevent the release of Styrene, MMA, and MDI. In addition, Aquatic operates an air pollution control system consisting of a Rotary Concentrator and Regenerative Thermal Oxidizer to effectively reduce air emissions by over 90 percent. Periodic testing and continuous monitoring of the control system are the primary means Aquatic uses to assure compliance.

¿Cómo controla ORCAA el cumplimiento?

ORCAA monitors compliance in many ways including, but not limited to, inspecting Aquatic at least annually, observing air emissions testing, reviewing semi-annual monitoring reports, and reviewing the performance of Aquatic’s control system by periodically reviewing operating data. ORCAA has regulatory authority to issue notices of violation and assess penalties.
