RAP Special Conditions Text: Special Conditions Permit Number XXXX 1. This permit authorizes emissions only from those emission points listed in the attached table entitled “Emission Sources - Maximum Allowable Emission Rates” (MAERT), and the facilities covered by this permit are authorized to emit subject to the emission rate limits on that table and other operating conditions specified in this permit. Also, this permit authorizes the emissions from planned maintenance, startup, and shutdown (MSS). Federal Regulations 2. The permitted sources at these facilities shall comply with all applicable requirements of the following federal regulations: A. The U.S. Environmental Protection Agency (EPA) Standards of Performance for New Stationary Sources (NSPS) in Title 40 Code of Federal Regulations (40 CFR) Part 60: (a) Subpart A: General Provisions (b) Subpart KKKK: Stationary Combustion Turbines (c) Subpart IIII: Stationary Compression Ignition Internal Combustion Engines B. The EPA National Emission Standards for Hazardous Air Pollutants (NESHAPS) for Source Categories in 40 CFR Part 63: (1) Subpart A: General Provisions (2) Subpart ZZZZ: Stationary Reciprocating Internal Combustion Engines 3. If any condition of this permit is more stringent than the regulations so incorporated, then for the purposes of complying with this permit, the permit shall govern and be the standard by which compliance shall be demonstrated.

RAP MAERT Emission Sources — Maximum Allowable Emission Rates Permit Number #### DRAFT date: April 18, 2017 This table lists the maximum allowable emission rates and all sources of air contaminants on the applicant's property covered by this permit. The emission rates shown are those derived from information submitted as part of the application for permit and are the maximum rates allowed for these facilities, sources, and related activities. Any proposed increase in emission rates may require an application for a modification of the facilities covered by this permit.
