    DOCUMENT NO: 363-2134-008 TITLE: Erosion and Sediment Pollution Control Program Manual EFFECTIVE DATE: April 15, 2000 AUTHORITY: Pennsylvania Clean Stream Law (35 P.S. §691.1 et seq.) and regulations at 25

    Pa. Code Chapter 102. POLICY: It is the policy of the Department of Environmental Protection (DEP) to provide

    guidance and procedures for those engaged in earth disturbance activities on ways to minimize accelerated erosion and resulting sediment pollution to the waters of the Commonwealth.

    PURPOSE: The purpose of this guidance is to tell those engaged in earth disturbance

    activities and in the preparation of erosion and sediment control plans how to comply with Chapter 102 rules and regulations.

    APPLICABILITY: This guidance applies to all those engaged in the preparation of erosion and

    sediment control plans for earth disturbance activities in the Commonwealth of Pennsylvania.

    DISCLAIMER: The guidance and procedures outlined in this document are intended to

    summarize existing requirements. The policies and procedures herein are not an adjudication or regulation. There is no intent on the part of DEP to give this document that weight or deference. The guidance and procedures merely summarize how and on what basis DEP will administer and implement its responsibilities with respect to erosion and sediment control on earth disturbance sites. DEP reserves the discretion to deviate from the guidance and procedures in this document if circumstances warrant.

    PAGE LENGTH: 180 pages LOCATION: Volume 34, Tab 6 DEFINITIONS: See 35 P.S. §691.1 and 25 Pa. Code Chapter 102 & 102.1.

    FOREWORD

    The various Best Management Practices (BMPs) described herein are primarily utilized during earth disturbances associated with land development and construction activities. Other special Best Management Practices for agricultural plowing or tilling activities which provide for the economic viability of farms, maintenance of the land, and protection of Pennsylvania waterways are described in the Natural Resources Conservation Services’ Pennsylvania Soil and Water Conservation Technical Guide. An overview of these Agricultural Best Management Practices is also provided in A Conservation Catalog Practices for the Conservation of Pennsylvania’s Natural Resources. Persons conducting agricultural plowing or tilling activities are encouraged to review the practices described in the Catalog and contact their local County Conservation District or Natural Resources Conservation District office for more detailed planning information and assistance. This manual lists various BMPs and design standards which are acceptable in Pennsylvania. BMPs, when designed according to these standards, and properly implemented and maintained, will achieve the regulatory standard of minimizing the potential for accelerated erosion and sedimentation. At the same time, their proper implementation will protect, maintain, reclaim and restore water quality and existing and designated uses of Commonwealth waters. Alternate BMPs, not listed in this manual, that provide the same (or greater) level of protection, may also be used to attain the regulatory standard. It is incumbent on the person proposing the use of alternative BMPs to demonstrate their effectiveness with appropriate test results or other documentation. BMPs that fail after installation must be repaired to function properly or be replaced by alternative BMPs that will serve the intended purpose. For example, if a skimmer in a basin or trap does not function as intended, it may need to be replaced by a perforated riser that does function as intended. Likewise, if unforeseen conditions occur on a site, and the installed BMPs are obviously not effective, then alternate BMPs must be designed and installed. The need for redesign will be determined on a case-by-case basis.
