SWPPP in Louisiana

SWPPP or Storm Water Pollution Prevention Plans is a written document which determines the possible sources of the storm water amidst the construction of the structure.  It also signifies certain practices that will mitigate the possible pollutant of storm water such as controlling the amount of water and initiating steps that will allow the water to settle in the soil.  It is also the document that determines the procedure that will be implemented by the contractor in order to be in compliance with the Construction General Permit.  An utter failure in the implementation of the SWPPP has a possibility to result in a considerable amount of fee from a Louisiana Environmental association or the EPA.  Here are the requirements on developing this plan.

Federal and State Requirement when Developing SWPPP in Louisiana

The federal regulation and the Clean Water Act is requiring almost all the operators in the construction site that are involved in excavating, grading and clearing activities that has a tendency to work in at least 1 acre or smaller construction site that is a part of the larger development to gain coverage on NPDES permit for their storm water.  Under this program, the EPA (Environmental Protection Agency) has the authority to implement the federal requirement when issuing permit.  Nowadays, most of the states are highly certified in implementing the program of NPDES, and they also issue their permit when it comes to Storm Water Pollution Prevention Plans that is associated with construction.

In Louisiana, under the Construction General Permit, there should be at least a single Storm Water Pollution Prevention Plans or SWPPP for every construction.  Operators or the owners are free to create a separate plan or a comprehensive plan that will cover the entire construction site.  When creating the SWPPP, it is highly required to include the following:

How do I Write SWPPP?

  • The Storm Water Pollution Prevention Plans should be duly signed by the authorized person that is in-charge of the construction. The signature should directly comply with the standards provided by the CGP of Louisiana.
  • Site description is also included in the SWPPP requirements, the practice of the construction and the manner of activities included in disturbing the land.
  • Sitemap should be incorporated to be SWPPP compliance. The sitemap should point out the location of the construction activities, the receiving water and the drainage area, management practices and others.
  • A detailed description of the construction as well as the waste materials that are going to be stored.
  • The control measure and the management practices that will be utilized during the project should be clearly specified.
  • It should include SWPPP inspections schedule and other maintenance activities that will occur during the construction.
  • It should also incorporate the permanent and interim method of stabilization which includes the schedule of execution and the specific location. In a more detailed aspect, the section of the SWPPP should clearly state the date of stabilization, the date of major land activity and whether there is a temporary or permanent stop in the construction.

Finally, it is highly recommended to keep the Storm Water Pollution Prevention Plans to be updated.  In case there are alterations when it comes to maintenance, operation, construction and design or things that have a significant impact on the project, the SWPPP in Louisiana should be updated.
