(conoco) Interoffice Communication to From D. D. Eoff T. J. Gross Date subject June 20, 1975 Investigation - Department of Transportation A U.S. Department of Transportation Safety Inspector, Mr. Collier H. Laws, visited the plant today with a list of safety and DOT violations and ir regularities pertaining to our vinyl chloride tank cars. Mr. Laws inspected the VCM cars at the Southern Pacific rail yard Wednesday, June 18. All cars noted were loaded the night of June 17. Three of the cars were loaded for the Aberdeen, Mississippi PVC Plant while the other three were loaded for Air Products in Pace, Florida. Below are the violations and irregularities noted by Mr. Law: UTLX 37302 - Containing Vinyl Chloride - - Liquid valve plug not in place. - Liquid valve and vapor valve plug loose. - Thermometer well cap loose. - Side safety railing loose, A-R. UTLX 37352 Containing Vinyl Chloride One liquid valve and vapor valve plugs loose. Thermometer well cap loose. Test tube (sample) valve plug missing. UTLX 37316 - Containing Vinyl Chloride - Both liquid valves and vapor valve plugs loose. - Thermometer well cap loose. - Side safety railing loose, B-R. UTLX 37301 - Containing Vinyl Chloride - One liquid valve plug loose. - Thermometer well cap loose. UTLX 37299 Containing Vinyl Chloride Both liquid valves and vapor valve plugs loose. Thermometer well cap loose. UTLX 37318 - Containing Vinyl Chloride - Both liquid valves and vapor valve plugs loose. - Thermometer well cap loose. CLfH 000001946 D. D. Eoff Page 2 June 20, 1975 Mr. Laws pointed out the Hazardous Material Regulation (Regulation 173.3 attached) that was violated. Mr. Laws also indicated that he would be inspecting VCM cars again in the near future to insure complete compliance with the regulations. Doyle Smith was contacted as a result of the DOT inspector's visit to the plant. In addition, a program is underway to develop and implement a preload checkout list and a post-load checkout list on each car. The checkout lists should help prevent similar occurrence of these types of deficiencies. T. J.

Interested persons were invited to par ticipate in this rulemaking proceeding and all comments received have been given full consideration by the Board. There were nineteen couamenters on the Notice Including representatives of the railroad Industry and shippers. The In terest shown and the comments ex pressed are appreciated by the Board. All of the respondentsvae of the opin ion that a regulation io. b*ad shields is premature and that a modified coupler design with n more positive means of preventing vertical displace ment of freight cars during impact would be preferable. The Board does not agree with this position for the following reasons: 1. Statistical evidence already exists through testing that a head shield would be both effective in reducing tank head punctures and would aim be cost bene ficial. There have been three studies on tank car head shields. Results of these studies are as follows: (a) The first study. Railroad Tank Car Safety Research and Test Project, Commission,* 1NCKNT J.

The same data base and statistical approach as used- in the RPI/AAR report was em ployed. The AAR assumed that the head shield would be only 50 percent effective and estimated the cost to be $272 for new cars and $474 for existing cars. On this basis, the net economic value was nega tive. On new cars the economic loss was stated as $8 and on existing cars the economic loss was $210. (c) Examination of the two reports by the FRA and the Calspan Corporation revealed that the separation of tank car punctures from other tank shell infusions accompanying or resulting from a head puncture may have caused bias in the data base discussed In (a) and (b) above. FRA totaled all shell punc ture damage and assigned the portion to head punctures based on the percentage of inr.idcnfcg originating from a head puncture. Application costs were based on the highest estimates from both head ghioiri reports, on this basis, the net value of the head shield is $395 on new cars and $201 on existing cars.
