2.2 bulk gasoline terminal Any gasoline storage and distribution facility that receives gasoline by pipeline, ship or barge, or cargo tank and has a gasoline throughput of 20,000 gal/day or greater. 2.3 equipment Each valve, pump, pressure relief device, sampling connection system, open-ended valve or line, and flange or other connector in the gasoline liquid transfer and vapor collection systems. This definition also includes the entire vapor processing system except the exhaust port(s) or stack(s). 2.4 gasoline cargo tank A delivery tank truck or railcar which is loading gasoline or which has loaded gasoline on the immediately previous load. 2.5 pipeline breakout station A facility along a pipeline containing storage vessels used to relieve surges or receive and store gasoline from the pipeline for re-injection and continued transportation by pipeline or to other facilities. 2.6 pipeline pumping station A facility along a pipeline containing pumps to maintain the desired pressure and flow of product through the pipeline and not containing storage vessels. 40 CFR Part 63, Subpart CCCCCC  , Section 63.11132, includes the following definition. 2.7 gasoline dispensing facility GDF Any stationary facility which dispenses gasoline into the fuel tank of a motor vehicle. While the regulatory definitions listed above are specific to gasoline, this publication applies to distribution and dispensing facilities for VOLs and is not limited to gasoline. 3 Emission Estimating Methods 3.1 Distribution Facilities 3.1.1 Overview AP-42, Section 5.2.1, gives an overview of the petroleum distribution system. Table 1 summarizes emission estimating methods for activities at distribution facilities. 3.1.2 Storage Tanks 220.127.116.11 Storing, Filling, and Emptying a VOL in a Storage Tank EPA offers software (TANKS) to estimate emissions from storage tanks.
18.104.22.168.1 Fixed-roof Tanks API MPMS Ch. 19.1 and AP-42, Section 22.214.171.124, provide emission estimating methods for fixed-roof tanks. The method given in each document is the same. 126.96.36.199.2 Floating-roof Tanks with Open Vents (Freely Vented) API MPMS Ch. 19.2 and AP-42, Section 188.8.131.52.1, provide emission estimating methods for floating-roof tanks with open vents. The emission estimating method for floating-roof tanks given in API MPMS Ch. 19.2 is the same as that given in AP-42, Section 184.108.40.206, with the following exceptions: 1) API MPMS Ch.19.2 specifies that the true vapor pressure of the stock is to be calculated from the average stock storage temperature (i.e. the liquid bulk temperature), whereas AP-42, Section 220.127.116.11, specifies that the true vapor pressure of the stock is to be calculated from the average liquid surface temperature; 2) API MPMS Ch.19.2 specifies a deck seam loss per unit seam length factor of 0.34, whereas AP-42, Section 18.104.22.168 specifies a deck seam loss per unit seam length factor of 0.14. 22.214.171.124.3 Closed-vent Internal Floating-roof Tanks (IFRTs) (Non-freely-vented IFRTs) As discussed in API 2569, emissions from closed-vent IFRTs may be approximated as 5 % less than emissions from IFRTs with open vents determined in accordance with 126.96.36.199 b).
