Specifications include, but are not limited to: Richmond Plant (Title V Permit) Solar Compressor C-5RA: The C-5RA gas turbine compressor is fired by natural gas and has a 12.53 MMBTU/hr capacity. The compressor was installed in 2004 and has a requirement for stack testing every five years, typically after the Richmond Plant Title V permit is renewed. The next test is anticipated in 2024. Test ports in the single 24” stack are accessible in an interior catwalk location. Fall protection is required to access the stack. Passyunk Plant (Synthetic Minor Permit) Nebraska Boilers: Three (3) 58.28 MMBTU/Hr Nebraska Boilers are currently in use at the Passyunk Plant. These steam boilers were put into service in 1994 and each has one (1) roof stack with a diameter of 36-inches. Test ports on the stacks are accessible via a man lift which will be provided by PGW. Fall protection is required to access the stack and the contractor must be qualified to operate the man lift. Stack testing is required on one (1) boiler every five years, typically after the Synthetic Minor permit is renewed. The next test is anticipated in 2027. Source level stack testing requirements are as follows per AMS-issued operating permits: -C5RA Gas Turbine Compressor: NOx by USEPA Method 7E -Nebraska Boilers: NOx by USEPA Method 7E and CO by USEPA Method 10 The proposer may be asked to perform additional stack testing on sources not listed above, as required by AMS on a case-by-case basis. This work will be performed on a time and materials basis pre-approved by PGW. The proposer on behalf of PGW shall submit to Philadelphia Air Management Systems (AMS) proposed stack testing protocol at least (60) days prior to the scheduled date for stack testing. Stack testing of the Nebraska Boilers must be conducted during the winter months and scheduled to coordinate with PGW’s LNG vaporization operations. Compliance determination shall consist of the arithmetic mean of results of three separate 60 minute runs for each source test using U.S.E.P.A Reference methods 7E and 10. The source test shall be consistent with U.S.E.P.A designated test methods and 25 PA Code 139. NOx and CO limits from the Richmond Plant Title V Permit and Passyunk Plant Synthetic Minor Permit are provided below: Solar Compressor C-5RA: Nitrogen Oxides emissions from compressor ID# 27 shall not exceed 0.0150 % by volume at 15% oxygen on a dry basis. Nebraska Boilers: Nitrogen Oxides (NOx) emissions from each boiler shall be limited to 0.1 pounds per MMBTU of heat input Carbon Monoxide (CO) Emissions from each boiler shall be limited to 0.15 pounds per MMBTU of heat input The Greenhouse Gas Leak Survey is performed to locate and identify leak sources within PGW Gas Processing operated locations including Richmond Plant Passyunk Plant Nine M& R stations throughout Philadelphia The inspections shall be conducted in accordance with United States Environmental Protection Agency (USEPA)Title 40 CFR Part 98, Subpart W. The results of this survey will be summarized and submitted to PGW.
