Louisiana SWPPP Template and Storm Water General Permit Compliance Plan

The Louisiana Department of Environmental Quality (DEQ) has finalized a revised General Permit for Storm Water Discharges Associated with Industrial Activity (Multi-Sector General Permit, or MSGP). This permit replaced the previous Louisiana general permit, which had expired. The Louisiana general permit is modeled after the US EPA MSGP and defines sector specific requirements for each of 29 different industrial sectors. For most facilities subject to the existing general permit, the revised MSGP will require a significant revision to the facility stormwater pollution prevention plan, or SWPPP.

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 Louisiana permit requirements, including Louisiana specific quarterly inspection checklist, quarterly visual assessment checklist, quarterly benchmark monitoring checklist, and an annual comprehensive site inspection checklist. Caltha has also prepared a Louisiana Stormwater Permit Compliance Plan to assist permitted facilities in organizing and planning new compliance requirements under the LDEQ general permit.
