National Pollutant Discharge Elimination System 

The National Pollutant Discharge Elimination System (NPDES) is a nation-wide permitting program that manages and controls the discharge of pollutants into the nation's waters, with the goal of keeping our rivers, lakes, and oceans clean. NPDES permits are required when construction activities will result in earth disturbance areas equal to or greater than one acre (or 43,570 square feet).

NPDES permit requirements are extensive, in terms of the forms, plans, and calculations that must be submitted with the NPDES permit application, as are the construction inspection requirements during a project and as-built certification requirements at the close of the NPDES project. Alta has successfully navigated this process for a number of projects in southeastern Pennsylvania. For one such project in Montgomery County, PA, the reviewing personnel at the Montgomery County Conservation District (which has jurisdictional authority for NDPES permits in Montgomery County) were so impressed by the plans that Alta submitted for a project that they asked us to provide for them a “generic” copy of those plans, for them to use as an “Example Project” for training purposes. Images of those "generic" plans can be viewed on our Example Alta-Developed Civil Engineering & Land Development Project & Plans page.

Feel free to CONTACT US to discuss your project and the permits and/or variances that may be required to make your plans a reality.
