Landfills closed and capped in accordance with MassDEP permits issued after 1990 may be good locations for post-closure development of facilities that use photovoltaic (solar) panels and/or wind turbines to generate electricity from these renewable resources. See the complete Landfill Post-Closure Use Permitting Guidelines, June 2009 pdf format of Landfill Post-Closure Use Permitting Guidelines doc format of Landfill Post-Closure Use Permitting Guidelines .

The 310 CMR 19.000: Solid Waste Management Facility Regulations pdf format of 310 CMR 19.000: Solid Waste Management Facility Regs (specifically Section 19.143: Post-Closure Use of Landfills) requires MassDEP Post-Closure Use Permits for projects of this type. 

MassDEP has established two permit categories for post-closure activities at landfills, depending on whether the reuse activity is classified as major or minor. To learn more, see the application form and instructions: BWP SW 36, 37 - Landfill Post-Closure Permit
