Best Management Practices for the Construction Industry

Appendix D

  • The general contractor, or if none, the property owner, shall be responsible for assuring that each contractor or subcontractor evaluates each site before construction is initiated to determine if any site conditions may pose particular problems for the handling of any regulated substances. For instance, handling regulated substances in the proximity of water bodies or wetlands may be improper.
  • If any regulated substances are stored on the construction site during the construction process, they shall be stored in a location and manner which will minimize any possible risk of release to the environment. Any storage container of 30 gallons, or 250 pounds, or more containing regulated substances shall have constructed below them an impervious containment system constructed of material of sufficient thickness, density and composition that will prevent the discharge to the land, groundwaters, or surface waters of any pollutant which may emanate from said storage tank or tanks. Each containment system shall be able to contain 150% of the contents of all storage containers above the containment system.
  • Each contractor shall familiarize himself with the manufacturer’s safety data sheet supplied with each material containing a regulated substance and shall be familiar with procedures required to contain and clean up any releases of the regulated substance. Any tools or equipment necessary to accomplish same shall be available in case of a release.
  • Upon completion of construction, all unused and regulated waste substances and containment systems shall be removed from the construction site by the responsible contractor and shall be disposed of in a proper manner as prescribed by law.
