Environmental Practices Guide (EPG)

This 46-page guide is intended to assist plant operators in operating and maintaining their facilities in a manner that minimizes potential environmental impact. It outlines a "best practices available" approach to environmental management but is not all-inclusive to cover all possible situations.

6th Edition

Environmental Practices Guide

The 6th Edition of the guide provides updated guidance for asphalt cement (AC) pumping and storage temperatures. AC pumping and storage temperatures have been combined into one category such that the recommended AC storage temperature range is the same as the recommended AC pumping temperature range. Guidance for the recommended HMA mixing temperature range has been added. Temperature ranges, which differed by AC grade in previous versions of the EPG, are now shown as common ranges for all grades. This change was made to reflect that asphalt binders of the same grade may have different properties depending on the government specifications that they are required to meet and that this may result in different storage, pumping, and mixing temperatures for binders of the same grade. Guidance for developing plant specific inspection checklists has been enhanced. An example of a checklist sorted by the areas in an asphalt plant is provided as in previous versions of the EPG. A new version of the checklist, sorted by inspection frequency, is now provided to enable users to use the version of the checklist which best suits their requirements.
