July , 200 0 Synopsis: The Department of Environmental

Protection (DEP) proposes to replace the existing permitting procedure for newboilers having an energyinput capacitybetween 10and 40million Btu per hour withprocess-specific performance standards and compliance certifications, under the Environmental

Results Program. The purpose is to simplifyand clarifythe regulatoryprocess, thus reducing the cost

and time required

to comply, while maintaining effective standards and improving environmental

results. The proposed standards require the use of

clean fuels, set

emissions limits, and specifyoperational

and record keeping requirements. Initial and annual compliance certifications, signed by a responsible official , must be submitted

to the DEPin accordance with310CMR 70.00. Also proposed is an amendment

to 310CMR 7.02 to exempt facilities that complywithERPfromplan application requirements. The proposed

amendments to 310CMR 7.02, 7.26 and 310 CMR 70.02 are attached to this document as an appendix.
