SWT  works with our clients and the appropriate regulators to provide cost-conscious, practical compliance solutions that meet the criteria required by regulatory agencies. SWT’s extensive knowledge and experience of Federal, State, and local requirements, regulatory documentation and reporting, engineering specifications, construction oversight, and environmental compliance enables our clients’ projects to be conducted in a timely manner.  

Permitting

SWT has provided various support services for many types of permits including:

 • Solid Waste Facility Permits (SWFPs)

        - Revisions, Modifications, and Amendments

 • Five-Year Permit Reviews

 • Conditional Use Permits (CUPs)

 • Industrial General Permit (IGP)

 • Waste Discharge Requirements (WDRs)

 • City- and County-Specific Permits (Environmental, Building, Fire, etc.)

 • California Environmental Quality Act (CEQA) Permitting

 • Resource Agency Permitting Support

Reporting

SWT provides preparation of various reports and documentation to meet regulatory requirements including, but not limited to:

 • Joint Technical Documents (JTDs)

 • Closure Plans (preliminary, partial, and final)

 • Reports of Composting Site Information (RCSIs)

 • Transfer/Processing Reports (TPRs)

 • Stormwater Pollution Prevention Plans (SWPPPs)

 • Spill Prevention, Control, and Countermeasures (SPCC) Plans

 • Notices of Non-Applicability (NONAs)/No Discharge Technical Reports

 • Non-Water Release Corrective Action Plans/Cost Estimates

 • Site Capacity Analysis/Aerial Budget Models

SWT has prepared several Notice of Non-Applicability (NONA) / No Discharge Technical Reports.  This has included determining a site’s eligibility for NONA basin(s), basin design, regulatory liaison throughout the process (i.e., preliminary concurrence prior to basin construction), NONA report preparation, Notice of Termination, and all related services.  NONA’s allow our clients added protection from third-party lawsuits, as well as long-term cost savings as NONA facilities are not required to sample stormwater and prepare other reports (i.e., SWPPP, Annual Reports, etc.).
