AASHTO FGMP-1:2016 Maintenance Stormwater Field Gufide.
Highways and other transportation-related sites can be a source of sediment and other pollutants to rivers, lakes, and coastal waters. Best management practices (BMPs) can be used by maintenance workers to reduce the discharge of pollutants from highway storm drain systems.
The intent of this guide is to be a quick reference for maintenance staff on topics related to BMP inspection and common operational practices. Good housekeeping and other pollution source control measures are presented. Using the tips in this guide will help in complying with federal and state regulations for stormwater quality. It will also help achieve a greater level of environmental stewardship. This guide is not a design manual or a substitute for a pollution prevention plan.
Preface to Readers
This publication includes descriptions of BMPs and how to maintain them. It is organized based on common highway and facility operational practices. Oftentimes a single BMP can be used for many different operations (e.g., street sweeping can be part of normal road maintenance, cleanup required after winter application of sand, and specialized bridge maintenance practices).
The information presented in this guide is based on techniques and control measures considered generally effective in many areas of the country. Local conditions may require that the practices discussed in this guide be altered, or used with other measures. This guide may also be augmented by DOTs to provide more information to suit local practices and field conditions.
The information provided for each BMP includes maintenance frequencies and performance standards. In all cases, this information is to provide guidance specific to highway and DOT facility operation. In no case is such information
meant to supersede, substitute for, or make more stringent well-defined practices or regulatory standards.
Clean Water Goals
DOTs conduct activities that can pose a threat to water quality if BMPs are not used. These activities include road maintenance, application of traction aides and de-icers, minor road and bridge repairs, fleet maintenance, landscaping, and facility maintenance. DOTs also conduct activities that remove pollutants from the storm drain when done properly, such as street sweeping and storm drain system cleaning.
Follow your DOT procedures for:
Using BMPs to treat pollutants from highway areas, transportation infrastructure, maintenance areas, storage yards, weigh stations, rest stops, and welcome centers, among others;
Developing inspection and maintenance procedures and schedules for stormwater BMP implementation;
Properly disposing of pollutants; and
Identifying ways to reduce water quality impacts associated with the most common maintenance and operational practices.
This guide provides practical information to DOT staff for selecting and using the most appropriate BMPs for each activity or situation.AASHTO FGMP-1 pdf download.
