Re: Freedom of Information Act Request RIN: HQ-RIN-1460-88 

Mr. Samuel A. Leonard, Director 

Automotive Emission Control 

Environmental Activities Staff 

General Motors Corporation 

General Motors Technical Center 

Warren, MI 48090 

Dear Mr. Leonard: 

This letter is in response to your letter of March 4, 1988 

making specific requests under the Freedom of Information Act. 

For clarity, the format used in your request will be used in 

the response, i.e., the numbering system which you employed in 

your request will be used, followed by the wording of your 

request and finally followed by our response to that request. 

General Motors Request #la 

"Any "testing," like that referred to on page 15 of EPA's 

March 1987 Summary and Analysis of Comments on the 

Recommended Practice for the Measurement of Refueling 

Emissions (the "Recommended Practice Analysis") that shows 

or relates to obtaining "repeatable loading conditions" 

during the onboard refueling emissions control test 

procedure proposed by EPA at 52 Fed. Reg. 31162 (August 

19, 1987);" 

The paragraph on page 15 of the "Recommended Practice 

Analysis" referenced in your request addressed a concern 

expressed by MVMA in prior comment on the test procedure. The 

concern expressed by MVMA was that the SHED procedure for 

detecting breakthrough coupled with a refueling rate of 

approximately 10 gallons/minute during loadings to breakthrough 

might cause the canister to be loaded significantly beyond 

breakthrough. While agreeing that detection lag could cause 

some loading past breakthrough, EPA stated that that was not 

troubling because the purpose of the procedure was to achieve 

loadings to at_ least breakthrough; i.e., the purpose of the 

canister loading is not to achieve an exactly repeatable

loading but, as stated in the preamble, to insure that the 

canister receives "a heavy, near saturation, loading." if 

repeatability was a concern EPA would have considered requiring 

the canisters to be loaded to the saturation point. EPA agreed 

to lower t^e fueling rate because loading to breakthrough would 

still be ^achieved. In arriving at this conclusion EPA 

referenced some testing which was being performed as an overall 

evaluation of the test procedure. Specific data was not 

included in the analysis because the testing was not directly 

targeted at an evaluation of a change in the dispensing rate. 

The test plan applicable to that testing and the check lists 

for use in the collection of test data can be found in the 

docket in supplemental docket material located in EPA's Public 

Information Reference Unit, 401 M Street, SW, Room 2904 under 

docket A-84-07 which was incorporated by reference into docket 

A-87-11. The specific document numbers are: B-00076, B-00689, 

B-00690, B-00691, B-01117, B-01118, B-01119, B-01121, B-01122, 

B-01123, B-01129, B-01130, B-01145, B-01153, and B-01400. 

Within these document numbers are some duplications of 

individual documents. To the best of our knowledge, we have 

identified all of the copies of the applicable documents which 

are in the PIRU materials. 

EPA has not yet completed an analysis of the test results, 

however the raw data as collected on the checklists, computer 

printouts of emission calculations, drivers traces, and FID and 

temperature strip charts are available. Copies of the 

checklists and computer printouts are enclosed (Enclosures 1 

through 4) in accordance with Mr. Timothy McCann's request. The 

other materials have not been copied (Mr. McCann's directive) 

but are available for your inspection should you so desire. 

General Motors Request #lb 

"The "data available to EPA" which indicate that vehicle 

emissions control systems do not" undergo permanent 

adverse effects by being highly loaded and quickly recover 

(their) capacity when vehicle operating conditions provide 

additional purge," or which indicate that the 

"breakthrough requirement ... provides a useful, readily 

identifiable point for beginning testing" as stated on 

page 17 of the Recommended Practice Analysis;" 

Test information used by EPA in making the judgments on 

the operational characteristics of carbon canisters was 

collected from evaporative emission canisters supplied to EPA 

by vehicle manufacturers. These canisters were removed from 

durability data vehicles, which to the best of our knowledge, 

had been in storage for some time prior to removal of the 

canisters. The test information collected by EPA is detailed 

in the Appendix of the "Recommended Practice Analysis." 
P.5

» 

In addition, it is recognized by EPA that in-use vehicles 

can undergo repeated diurnals when the vehicles are out of use 

for some period of time. Under such real world conditions, 

repeated diurnal loadings will cause evaporative canisters to 

become ful^ly loaded. We believe these fully loaded canisters 

recover their capacity to store hydrocarbons, without lasting 

degradation in their performance, once the vehicle is driven 

and purging of the canister occurs. If you believe otherwise, 

we would be most interested in seeing any information available 

to General Motors which shows that evaporative canisters do not 

recover their storage capacity with purging following repeated 

diurnals. 

General Motors Request ttlc 

GM statement: "Any data available to EPA which "suggests 

that...premature puffs of vapor may not be a significant 

concern" during canister loading pursuant to either 

proposed sections 86.132 or 86.232 of EPA's proposed 

onboard refueling or evaporative emissions test 

procedures, see 52 Fed. Reg. at 31245, 31250-51, 31349-50, 

as stated on page 14 of the Recommended Practice Analysis;" 

As you know, we did not propose a non-SHED procedure 

because of concerns such as were identified in the quoted 

passage. The "data" referred to consisted only of observations 

of FID output readings when the FID sample pickup was located 

at the canister outlet while the canister was being loaded with 

butane. These observations were preliminary indications from 

some of the canister testing which was conducted to identify 

the purge characteristics of the canister. There was no 

definitive data which could be cited since we had not conducted 

any specific evaluation directed at verifying whether a 

non-SHED procedure was viable. If we had, a more definitive, 

position would have been included in the proposal. 

General Motors Request ttld 

"The methodology and equipment used in the testing that 

produced the data described in the preceding subparagraphs 

of this request, and any plans to conduct similar testing." 

The methodology used in the testing identified under 

General Motors request *la is identified in the test plan and 

checklists previously l:sted in the response to that request. 

The test methodology .tiiized in the testing identified under 

General Motors request tub is reported in the Appendix of 

"Recommended Practice Analysis." The methodology used in the 

testing identified ..r.ier General Motors request #lc was 

explained above in the response to that question. The 

equipment used in all of the testing is standard test equipment 

available in the EPA laboratory; i.e., a SHED, FID, scale for 

canister weighings, pux.p and dry-gas meter used to purge 

canisters and measure,, volume of purge air, plumbing to 

interconnect equipment as needed, bottled butane when required 

for canister loading and either a fuel cart or facility fueling 

equipment when required for vehicle fuelings.

With respect to your query on plans to conduct similar 

testing, we expect that we will evaluate "new" or "improved" 

activated carbons as these materials become available from 

manufacturers of these materials. We would expect to make such 

data available if it appears relevant to the rulemaking. 

General Motors Request #2 

"All records that refer or otherwise relate to the 

Agency's finding that the proposed 0.10 gram/gallon 

standard for onboard refueling emissions control systems 

will or could "allow sufficient leeway for any measurement 

variability" or for other types of "testing variability," 

as stated in 52 Fed. Reg. at 31190-91, or to testing 

conducted or planned to assess testing variability." 

The materials used by EPA in arriving at the conclusions 

stated in the preamble to the onboard NPRM and identified in 

your request were identified and referenced in the preamble. 

The documents identified were references 13 ("Evaluation of the 

Feasibility of Liquid Fillneck Seals," U.S. EPA, OAR, OMS, 

ECTD, EPA-AA-SDSB-86-3, December 1986) and 14 ("Vehicle Onboard 

Refueling Control," American Petroleum Institute, March 1986, 

API Publication No. 4424) and the results of "recently 

performed refueling" performed by General Motors. These 

documents can be found in the docket as items II-A-12, II-D-04, 

and document B-01317 in the PIRU materials. 

I believe that the above responses adequately respond to 

your requests. I am also enclosing our billing in accordance 

with the Freedom of Information Act. 

Sincerely yours. •

1G3AH69A7DM42094 

Two Objectives: l) Is the new procedure workable? Provide comments. 

2) Collect data on refueling emissions, canister weights & time requirements. 

RVP Samples: Request RVP samples when the cart has been filled, and if 

more than three days have passed, just before it is to be refilled. Run 1.3 

to.2 gallons of fuel through the nozzle back into the cart just before sampling 

so the sample is representative of the fuel in the cart rather than just the // A/ // 

nozzle. Inform Bill Pidgeon each time a sample has been requested.

Use the following 8 instructions to record the data in spaces provided below the 

procedure: 

1. Place vehicle in SHED and record time. 

2. Turn off purge blower, turn on enclosure's mixing blower and close doors. 

3. Record fuel tank temperature after closing doors (thermocouple *l). 

4. Record background SHED FID just before refueling begins. 

5. Refuel vehicle with the flow rate at about half of maximum (3-4 gal/min) 

by using the xnjddjg^oieh of the trigger holding lever. If the SHXD FID 

reading increase s by a factor of 3 withi n one minute,

Two Objectives: l) Is the new procedure workable? Provide comments. 

2) Collect data on refueling emissions, eanister weights A time requirements. 

gyp S^nnnlf - Request RVP samples when the cart has been filled, and if 

more than three days have passed, just before it is to be refilled. Run 1.5 

±0.2 gallons of fuel through the nozzle back into the cart just before samphag 

so the sample is representative of the fuel in the cart rather than just the 

nozzle. Inform Bill Pidgeon each time a sample has been requested.

Use the following 8 instructions to record the data in spaces provided below the 

procedure: 

1. Place vehicle in SHED and record time. 

2. Turn off purge blovrer, turn on enclosure's mixing blower and close doors. 

3. Record fuel tank temperature after closing doors (thermocouple *l). 

( 4. j^ecord background SHED FID just before refueling begins. 

5. Refuel vehicle with the flow rate at about half of maximum (5-4 gal/min) 

by using the middle notch of the trigger holding lever. If the SHJU> FID 

reading inoreases by a factor of I within one minute , 

breakthrough has occurred and the flow must be stopped 

immediately - us e two technicians if a single technician can not 

simultaneously watoh the FID reading and hold the nonle . For 

premature shutoffs, continue filling at half of maximum flow rate until 

approximately 95% is attained. 

6. If breakthrough does not occur, during the first fueling, open SHED 

and begin fuel tank draining within 10 minutes of completing the first 

fueling. Purge SHED while draining tank Repeat the procedure until 

breakthrough occurs. 

7. Record other data, including canister weight and fuel tank temperature 

(thermocouple *l) after each refueling, as asked for below. 

8. Repeat steps 1 through 7 until canister breakthrough occurs.
