AS? NIGERIAN MIDSTREAM AND ).¢ DOWNSTREAM PETROLEUM Bet? REGULATORY AUTHORITY (NMDPRA) Applicable to all Midstream and Downstream Petroleum Operations GUIDELINES FOR MANAGEMENT OF GREEN HOUSE GASES (GHG) AND FUGITIVE EMISSIONS FROM MIDSTREAM AND DOWNSTREAM PETROLEUM OPERATIONS IN NIGERIA a. Replacement of rod packing on or before compressor has operated for 26,000 hours, or prior to 36 months from the date of the most recent replacement, whichever comes first. Within 36 months from the start-up date, the rod packing of a new reciprocating compressors shall be replaced. b. Collection of methane and VOC emissions from the rod packing using a rod packing emissions collection system which operates under negative pressure and routes the emissions to a process through a closed vent system. 3.8.2 Monitoring As part of instrumental LDAR, a licensee or permit-holder shall inspect compressor seals, rod-packing and Vapor Recovery Systems, every 90 days. 3.8.3 Reporting A licensee or permit-holder shall submit an annual report not later than 90 days of the preceding year, stating level of compliance and record of any deviations, along with certification of the truth and accuracy of report signed by a competent person. 3.9 Glycol Dehydrators 3.9.1 Requirements for Control a. A condenser or air pollution control equipment shall be used in the reduction of uncontrolled actual emission of hydrocarbon by at least 95% (on a Continuous 12-month cycle) from still vents and vents from any flash fank on a glycol natural gas dehydrator located at natural gas compression station, or gas-processing plant. Where a combustion device is used, it shall have a design Destruction and Removal Efficiency of at least 98% for hydrocarbons. 25
