Proposed Amended Rule (PAR) 1149 - Storage Tank and Pipeline Cleaning and Degassing

Proposed Amended Rule (PAR) 1149 - Storage Tank and Pipeline Cleaning and Degassing

PAR 1149 would implement the 2007 AQMP control measure FUG-04 - Further Emission Reductions from Pipeline and Storage Tank Degassing, to achieve additional VOC emission reductions. PAR 1149 would extend the applicability of the rule to small above ground organic liquid storage tanks, pipelines, and large storage tanks previously exempted because of lower vapor pressure products. The current rule requires vapors contained in storage tanks to be vented to a control device for a pre-determined length of time or to be displaced by a liquid into a control device. PAR 1149 would instead require a vapor concentration of 5,000 ppmv, measured as methane, before vapors are vented to atmosphere. PAR 1149 would streamline the notification process and clarify requirements for vacuum trucks and containers used for storing liquid and sludge removed during the cleaning process. PAR 1149 introduces a greenhouse gas (GHG) quantification protocol, where GHG emissions may be voluntarily reduced by controlling methane emissions from natural gas pipelines.
