13、tiary storage is defined to be all inventory held in customer tanks. All propane held in retailer storage tanks or customer storage tanks will ultimately be consumed. Furthermore, all volumes of propane in retailer and customer storage tanks (production, primary inventory, imports) are captured by E
14、IAs data collection system and will not be returned (in any significant volumes) into the primary supply distribution system. However, a few petrochemical companies have private storage facilities. These facilities are generally underground salt cavern storage and are connected via pipeline to prima
15、ry storage facilities, such as those in Mont Belvieu. Propane stored in private salt caverns may be returned to primary storage. When inventory from private salt cavern storage is returned to the primary distribution system and immediately sold into the market, the EIA data collection system will no
16、t capture these volumes in its annual summary of propane supply. In 2014, PERC receipts, raw survey data and other analyses indicated substantial volumes of uncounted supply were delivered into the primary distribution system and were immediately redelivered into the market. The results of the 2014
17、propane sales survey include an adjustment to U.S. propane supply statistics published by EIA in the Petroleum Supply Annual for 2014. 2014 Sales of Natural Gas Liquids and Liquefied Refinery Gases 2016 The American Petroleum Institute.

31、a l l o n s )D i s t ri ct API refers to them as multi-state retailers 2. All other propane retail marketers; API refers to them as single-state retailers but understands that they may operate in more than one state. The response rate for multi-state retailers is considered to be 100%, therefore no
32、adjustment or estimation is needed. The estimation methodology therefore centers on single-state retailers. API estimates the Propane sales for the single-state retailers then appends the volumes to the reported retail propane sales gallons from large retailers to arrive at the estimated total propa
33、ne sales for each state. Therefore, all further discussion will center on the estimation methodology used to calculate the single-state data and will ignore the multi-state data. II. Estimation Methodology Step 1 Collecting Publicly Available Data Retail sales of propane data for total U.S., by PADD
34、, and, whenever possible, by end-use are collected from publicly available sources. Much of the data on the PADD level (and even some state detail) are available publicly from Energy Information Administration (EIA) and Petral Consulting Company. Depending on the time of the year, API can obtain the
35、 following data: 1. Total Propane Sales by PADD 2. Propane sales to Chemical plants by State These data are therefore with one minor adjustment - not estimated by API but used to calculate the sales by end use for each state. Historically, propane import statistics published by EIA and the Foreign T
36、rade Division/Census Bureau were in close agreement. Furthermore, propane import statistics published by the National Energy Board of Canada were also in close agreement with Foreign Trade Division/Census Bureau statistics. In 1993, however, EIA statistics for propane imports were 39.1 M Bpd less th
37、an Foreign Trade Division statistics. Since 1993, EIAs published data for propane imports have been chronically less propane imports as published by the Foreign Trade Division/Census Bureau. The understatement of imports is typically in the range of 25-50 M Bpd. Based on a detailed review of PADD le
38、vel propane import statistics, EIA statistics consistently understate Canadian propane imports into PADD 1 and PADD 2. The understatement of propane imports causes EIA statistics to understate total propane supply especially in PADD 1 and PADD 2. EIA propane supply statistics are critical to the pre
39、paration of the annual report of propane sales by end-use category. In particular, EIAs undercount of propane imports would cause propane sales into the residential/commercial markets to be understated if total propane supply statistics were not adjusted to reflect this chronic undercount problem. H
40、ence, EIAs published propane supply statistics are adjusted to reflect the understatement of Canadian propane imports. The adjustment to EIA propane supply statistics improves the quality of the propane end-use sales presented in the annual Sales of Natural Gas Liquids and Liquefied Refinery Gases.
41、In 2004, concern about EIAs accurate measuring of PADD to PADD transfers of propane were heightened when reported data exceeded the EIA PADD total for the first time. It was therefore determined that better overall estimates could be achieved if regional PADD controls were lifted and the total U.S.
42、number was used. In essence to keep the nomenclature of this methodology unchanged all the states were considered to belong in one PADD and the estimated states totals were rolled up directly to the U.S. totals, not the PADD totals.APPENDIX A 2014 Sales of Natural Gas Liquids and Liquefied Refinery

While API may receive responses from 10 of 15 retailers from Alabama, there may only be 2 of 20 responses from Virginia. In general, response rate
44、s for this survey are between 40 and 95 percent within a state these rates are sufficient to give API a high confidence in its estimates. Assuming that response within a state is independent of volume (a detailed discussion of this assumption can be found in section III. Methodology assumptions and
45、caveats), we can adjust the total reported numbers within each state as follows: Adjusted total reported propane sales by state = Tj =jjncc nNP 1Where, P = Total reported retail propane sales volumes per company n = Number of respondents in this state N = Number of surveys sent to this state c = A r
46、esponding company j = A state Step 3 Estimating Total Retail Propane Sales by State At this point, we have two estimates for each PADD: 1. The publicly available PADD total (from EIA) 2. The estimated PADD total reached by adding the estimated state totals calculated in step 2 above. The difference
47、between the two totals is simply the normal variance one observes, as an estimate is calculated using two different estimation methodologies. API has decided that the publicly available numbers, unless the difference between the two numbers is substantial1, are the ones to use in this publication. W
48、e must therefore adjust the estimated state totals calculated in step 2 above to add-up to the publicly available total for each PADD. Again, we use proportional allocation to reach our estimates as follows: Estimated total propane sales by state = Ej = knjjkjk DTT 1Where, k = PADD number (k = 1 to
49、5) Tj = Adjusted total reported Propane sales by state (see step 2 above) D = Total Estimated Propane sales in that PADD j = A State n = Total number of states in that PADD 1 The definition of the word “substantial”, which is also mentioned in a later section of this methodology, is left to the statistician working on the problem to define (based on the relative data in question). Another way to explain it is by using the phrase “statistically significant”. APPENDIX A 2014 Sales of Natural Gas Liquids and Liquefied Refinery
