(a) The agency of transportation shall work with municipal representatives to revise the agency of transportation's town road and bridge standards in order to incorporate a suite of practical and cost-effective best management practices, as approved by the agency of natural resources, for the construction, maintenance, and repair of all existing and future state and town highways. These best management practices shall address activities which have a potential for causing pollutants to enter the groundwater and waters of the state, including stormwater runoff and direct discharges to state waters. The best management practices shall not supersede any requirements for stormwater management already set forth in 10 V.S.A. §§ 1264 and 1264a that apply to state and town highways. The agency of transportation shall report to the house and senate committees on transportation, the house committee on fish, wildlife and water resources, and the senate committee on natural resources and energy by January 15, 2011, on the best management practices to be incorporated into the agency of transportation's town road and bridge standards.

(b) Beginning January 15, 2013, and every four years thereafter, the secretary in consultation with municipal representatives and with approval from the agency of natural resources shall review and revise, as appropriate, town road and bridge standards in order to ensure the standards are protective of water quality. (Added 2009, No. 110 (Adj. Sess.), § 17, eff. May 18, 2010.)
