Highway and street maintenance is a diverse and complex set of undertakings: pavement crack and joint scaling; bridge painting; snow and ice control; erosion control; roadside vegetation management; and light, sign, and traffic signal repair and replacement. Pertinent environmental issues cut across all areas of public and regulatory concern including air quality, water quality, wetland and habitat preservation, noise, and energy usage. Moreover, driver safety and the occupational health and safety of maintenance personnel are critical issues. This report contains BMPs that fall into three categories: (1) High-level, broad-based BMPs applicable to an entire maintenance program--planning, programmatic environmental analysis, pollution prevention programs, classification of generated wastes in the conduct of site reviews or audits, and the development of a comprehensive training curriculum that addresses maintenance related environmental issues. These BMPs may be undertaken by managers of a department-wide level; (2) BMPs pertinent to specific maintenance activities or program areas--winter operations, vegetation management, bridge maintenance, buildings and ground maintenance, vehicle maintenance, collection of litter and debris, and maintenance of signs, striping, and markers; (3) BMPs pertinentuto specific environmental issues--hazardous wastes, wildlife and habitat, water quality, and noise. |
