The city of Dryden is one of these local governments that banned horizontal hydraulic fracturing via a zoning law [30]. A natural gas production company filed suit against the city claiming that the municipality was overstepping its jurisdiction. In early 2012, a state superior judge ruled that the municipality was not preempted by state laws and had the right to tighten its land use regulations. Zoning bans by local governments across New York send a strong message about local disapproval of hydraulic fracturing and have established a precedent for other municipalities to limit the drilling rights of oil and gas. | Roofing Materials Contributions to Storm-Water Runoff Pollution Shirley E.

Kirby Abstract Development in sensitive watersheds continues to pose environmental problems for receiving waters. One contributor to this long-term pollution is building and other construction materials. However the long-term effect of many building materials on the environment has not been quantified due to limited testing of these materials prior to sales and installation. Laboratory leach testing of commercially available roofing materials by this research group indicated that the potential for release primarily nutrients lighter hydrocarbons pesticides and metals is substantial. Testing of metals release from aged roofing panels also has shown that the potential for pollutant release still exists after 60 years. The data missing from a complete evaluation of many roofing materials is behavior over the lifespan of the material including the critical period of initial exposure. The 2 years of runoff data from a pilot-scale testing of these materials indicated substantial concerns regarding zinc from uncoated galvanized metals and copper from treated woods in this early part of the materials lifespan plus the potential for long-term nutrient releases in the runoff from several roofing types.
