Glossary & FAQ

                                           What Is Erosion?                     

Erosion is a natural process by which the surface of the land is worn away by water, wind or chemical action.  Accelerated erosion is the removal of the surface of the land through the combined action of human activities and natural processes at a rate greater than would occur from natural processes alone.

What is Chapter 102?

Montgomery County Conservation District, under a delegation agreement with the Pennsylvania Department of Environmental Protection, is responsible for reviewing Erosion and Sediment Control Plans and inspecting sites for Chapter 102 compliance.  For complete guidelines, refer to the Pennsylvania Code, Title 25. Environmental Protection, Chapter 102 Erosion and Sediment Control

What is an Erosion & Sediment Control Plan?

An Erosion and Sediment Control Plan, which meets the requirements of the Chapter 102 regulations must be properly designed, implemented, and available on site for all earth disturbance activities over 5000 sq. ft.  All construction activities proposing to disturb between one and five acres with point source discharge to surface waters of the Commonwealth, or projects disturbing five or more acres of land must be authorized by a National Pollutant Discharge Elimination System (NPDES) permit.

What is National Pollutant Discharge Elimination System (NPDES)?

The National system for issuance of permits under section 402 of the Federal Clean Water Act (33 U.S.C.A. § 1342) including a state or interstate program which has been approved in whole or in part by the Environmental Protection Agency.

*Although an E&S plan review for adequacy by County Conservation District is not required under the Chapter 102 Regulations, E&S review may be required by municipal ordinances, County requirements, or other Department of Environmental Protection/Army Corps of Engineers permit (i.e. - Chapter 105, Joint Permit, or GPs). 

** A meeting with the County Conservation District is recommended to verify there is not a point source discharge.

*** PCSM plans for General NPDES permits will receive a completeness review by the County Conservation District.  PCSM plans for Individual NPDES permits will be reviewed by the DEP regional office.

What is a Point Source Discharge?

Point Source is defined in Chapter 92 Section 92.1 as any discernable, confined and discrete conveyance, including, but not limited to, any pipe, ditch, channel, tunnel, conduit, well, discrete fissure, container, rolling stock, CAFO, landfill leachate collection system, or vessel or floating craft, from which pollutants are or may be discharged.

What are Surface Waters of the Commonwealth?

Surface waters are defined by Chapter 92 Section 92.1 as perennial and intermittent streams, rivers, lakes, reservoirs, ponds, wetlands, springs, natural seeps and estuaries, excluding water at facilities approved for wastewater treatment such as wastewater treatment impoundments, cooling water ponds and constructed wetlands used as part of a wastewater treatment process.

What is a Water of the Commonwealth?

Waters of the Commonwealth are defined in Chapter 102 Section 102.1 as rivers, streams, creeks, rivulets, impoundments, ditches, water courses, storm sewers, lakes, dammed water, ponds, springs, wetlands and all other bodies or channels of conveyance of surface water, or parts thereof, whether natural or artificial, within or on the boundaries of this Commonwealth.

What is a Post-Construction Stormwater Management Plan (PCSM Plan)?

A site specific plan identifying Best Management Practices (BMPs) to manage stormwater runoff after construction activities have ended and the project site has been permanently stabilized to protect and maintain existing and designated uses. The PCSM plan should be designed to maximize volume reduction technologies, eliminate or minimize point source discharge to surface waters, preserve the integrity of stream channels, and protect the physical, biological and chemical qualities of the receiving surface water.  The PCSM Plan must contain a written narrative, including calculations or measurements, and justifications for each  BMP.
