IA Stormwater Permit And Compliance Consultant- SWPPP Engineer

Caltha LLP maintains a library of SWPPP Templates developed to meet the requirements of individual States, including Iowa. Separate stormwater plan templates are provided to Industrial, Municipal (MS4) and Construction stormwater dischargers. Our Iowa SWPPP templates are updated to meet new State permit requirements as new or revised permits are finalized.

To reduce the level of effort required for facilities to come into compliance with new permit requirements, Caltha LLP has prepared a SWPPP template based on Iowa Department of Natural Resources (IDNR) permit requirements, including site specific quarterly inspection checklist, quarterly visual assessment checklist, quarterly benchmark monitoring checklist, and an annual comprehensive site inspection checklist. Caltha has also prepared a State Stormwater Permit Compliance Plan to assist permitted facilities in organizing and planning new compliance requirements under the stormwater general permit.

The revised SPCC Rule now allows the use of streamlined SPCC plan formats if facilities meet certain criteria. These streamline SPCC Template plans do not need to be signed by a professional engineer in most States. Other SPCC plans may need to be reviewed and signed by an engineer. Caltha LLP also provides SPCC training for companies subject to the SPCC Rule and conducts SPCC inspections.
