2003 SPECIFICATIONS

SECTION 110

SECTION 110 ABATEMENT OF WATER POLLUTION AND EROSION CONTROL

110.01 General. Abatement of water pollution and control of erosion is of great concern to all those in the highway construction industry. Work in or around streams and wetlands may fall under the jurisdiction of the U. S. Corps of Engineers, the Environmental Protection Agency, and/or other federal or state agencies. Section 110 of the Standard Specifications contains specific requirements for erosion control and abatement of water pollution. Resident Engineers should become thoroughly familiar with this and use it as a reference.

As stated in Section 110 of the Standard Specifications, erosion control is to be performed throughout the project as shown on the plans or as ordered by the Engineer. Permanent erosion control measures are to be completed as soon as practicable. Temporary erosion control measures are to be applied as needed to prevent, as far as practicable, erosion during construction prior to installation of permanent measures.

Often the control methods specified in the plans may not be effective for a particular situation or an area is not addressed by the plans. In such circumstances, the Resident Engineer should use his expertise and training to develop and implement appropriate and effective erosion and sediment control measures and fully document these changes to the Storm Water Pollution Prevention Plan (SWPPP). If the Resident Engineer is unable to develop a solution to the problem, he may contact Environmental Division for assistance in developing an appropriate solution to the problem.

Requirements.

General.

The

Arkansas

Highway

Commission has adopted the Department's "Erosion and Sediment Control Design and Construction Manual" (E & SC Manual) for use by Department personnel. While it is not a Specification, it helps to define the Department's policies with regard to compliance with current National Pollutant Discharge Elimination System (NPDES) requirements. Resident Engineers and their personnel should all become thoroughly familiar with this document and use it as a reference. In addition, the E & SC Manual serves as the core document for each permitted project’s Storm Water Pollution Prevention Plan (SWPPP). As such, a copy must be retained on each permitted project, along with project specific

portions of the SWPPP. Refer to the 2004 E & SC Manual for details.

The applicable notice, one similar to those shown in Figure 110-1, must be posted on the project bulletin board for ALL projects with an NPDES permit. Blank versions of these forms are available on the Construction Directory of the LAN at CSD4\misc\npdes\. If the project does not have a bulletin board (state projects, etc.), the notice should be posted in a prominent location for public viewing.
