Spring Environmental provides knowledgeable assistance with an assortment of permitting needs across multiple industries.


  • New Source Review / Notice of Construction / Permit to Construct:
    New Source Review (NSR) permitting [also known as Notice of Construction (NOC) or Permit to Construct (PTC)], requires stationary sources of air pollution to get permits before they begin construction. The permits detail what construction is allowed, what emission limits must be met, and how the source must be operated.
  • Title V Air Operating Permits:
    Title V applies to “major sources” of air pollution based on facility wide potential to emit. Operating permits encompass all regulatory requirements applicable to the facility including emissions limits, monitoring, reporting, and record keeping.
  • Synthetic Minor:
    A Synthetic Minor Operating Permit is a legally binding permit allowing a facility to lessen the extensive requirements for a major source facility by incorporating terms and conditions that lower the facility’s potential to emit air contaminants to below the major source thresholds.

Spring Environmental has extensive experience assisting clients with their permitting needs, including air quality modeling, emission calculations, determination of applicable regulatory requirements and preparation of permit applications.

Project Examples:

  • Stimson Lumber?…
  • Spunstrand AOP…
  • Miles Sand & Gravel is a construction company with portable and stationary plants. Spring Environmental has assisted with permitting multiple concrete batch plants in multiple regulatory jurisdictions throughout the Northwest. Services provided included identifying and quantifying emissions, preparing air modeling, preparing Best Available Control Technology (BACT) analyses and permit applications, and negotiating with regulatory agencies.


  • Wastewater Permitting:
    Water pollution can degrade surface waters making them unsafe for drinking, fishing, swimming, and other activities. The National Pollutant Discharge Elimination System (NPDES) permit program controls water pollution by regulating sources that discharge pollutants, either directly or indirectly, into waters of the United States.Spring Environmental provides assistance with the wastewater discharge permitting process, including effluent characterization, identification of monitoring and reporting requirements and preparation of the permit application package.

    Project Examples:

    • Vaagen Bros. Lumber is a lumber mill located in Colville, WA. Spring Environmental prepared a permit application to transition the facility’s wastewater discharge from a State Waste Discharge Permit to a new National Pollutant Discharge Elimination System (NPDES) Permit. Spring Environmental negotiated the final permit with the regulatory agency and assisted the facility with ensuring that monitoring and recordkeeping requirements were fulfilled.
  • Stormwater Permitting:
    Activities that take place at industrial facilities are often exposed to the weather. As runoff from rain or snowmelt comes into contact with these activities, it can pick up pollutants and carry them to a nearby storm sewer system or directly to a river, lake, or coastal water. To minimize the impact of stormwater discharges from industrial facilities, the NPDES program includes requirements for industrial stormwater permitting.Spring Environmental helps our clients with their Stormwater permitting needs, including the determination of Best Management Practices (BMPs) to effectively minimize pollutant discharges, development of Storm Water Pollution Prevention Plans (SWPPP), and preparation of permit applications.

    Project Examples:

    • Sand and Gravel Client…Peak Sand & Gravel is a sand and gravel company with multiple portable rock crushing plants. Spring Environmental has developed stormwater permits for all of the portable rock crushing plants for operation in multiple jurisdictions. Spring Environmental developed Site Management Plans, including Spill Control Plans, Monitoring Requirements and Stormwater Pollution Prevention Plans, to ensure site-specific coverage for each of the plants.
    • Industrial Stormwater Client…Michelsen Packaging is a manufacturer and distributor of supplies for the tree fruit industry based in Yakima, WA. Spring Environmental assisted Michelsen Packaging with preparation of their Stormwater Pollution Prevention Plan. In addition, Spring Environmental assisted with the identification of Best Management Practices, which included installing stormwater infiltration pavers to prevent site stormwater run-off.
