Shell Oil Comps: ( .. p;a.-a '32' i'ex-'i 772:3 February 24, 1989 139-704 3 'TM > n s -Kiijnv Mr. J. A. Niemeyer Manager, West Coast Division Shell Pipe Line Corporation P.0. Box 4848 Anaheim, CA 92803 Dear Mr. Niemeyer: PLAINTIFF'S EXHIBIT SUBJECT: HISTORICAL EXPOSURE POTENTIAL TO ASBESTOS AND BENZENE Per the service agreement between Shell Oil Company and Shell Pipe Line Corporation (SPLC), and at the request .of the SPLC West Coast Division (WCD) Safety Representative, C. W. Lowery, an evaluation of employees' past exposure potential to asbestos and benzene was done by D. L. Tackett, Industrial Hygienist II, HS&E, S&IH. The request was a result of an HS&E Medical Compliance Assessment Review recommendation to review medical surveillance requirements based on past exposure. A visit to the division's Northern District was made during the week of October 31, 1988. Current employees familiar with the past work practices for asbestos or benzene were interviewed to collect information on past handling practices, frequency and quantity of use, task duration, the years the material was in use, and use of personal protective equipment. Industrial hygiene sample data is not available for evaluating past exposures to asbestos or benzene within the division. The information collected during the district visit was reviewed by D. L. Tackett, J. D. Ransdell, Staff Industrial Hygienist, HSJE, S&IH, and P. J. Snyder, Staff Industrial Hygienist, Products, Health and Safety. Discussed below are the consensus findings and recommendations of the review by this group. ASBESTOS The OSHA asbestos standard does not include specific requirements for including employees in a medical surveillance program based on past exposures (29 CFR 1910.1001). However, there is a Shell Asbestos Medical Surveillance Program which does address past employee exposures. The program states that: Employees, who can be identified as having job assignments in the past, in which exposures can be determined as probably exceeding 0.1 fibers, longer than 5 micrometers, per cubic centimeter (TWA) or greater (regardless of respirator usage), on a reasonably predictable and repeated basis, shall also be included in an annual asbestos medical surveillance program. LAM 023927 CAS39040C4 ABS-007109 c - Employee training programs for asbestos have not sufficiently emphasized the known synergism between asbestos exposure and smoking. Objective Revise existing asbestos medical surveillance policy in order to correct any deficiencies and fully address the concerns described above. Policv - Employees whose present job assignment results in exposures to asbestos of 0.1 fibers, longer than 5 micrometers, per cubic centimeter (TWA) cr greater (regardless of respirator usage), on a reasonably predictable and repeated basis,* shall be included in Shell's annual asbestos medical surveillance program. -- - Employees, who can be identified as having had job assignments in the past, in which exposures can be determined as probably exceeding 0.1 fibers, longer than 5 micrometers, per cubic centimeter (TWA) or greater (regardless of respirator usage), on a reasonably predictable and repeated basis,* shall also be included in an annual asbestos medical surveillance program. - Available exposure data indicate that exposures during "ripout" or removal of asbestos-containing insulation may exceed 0.1 fibers per cubic centimeter. Accordingly, all employees, regardless of job title, whose work assignments now or in the past, would involve "ripcut" or removal of asbestos-containing insulation, on a reasonably predictable and repeated basis,* are to be induced in an annual asbestos medical survei11ance' program. - Employees who have been in an asbestos medical surveillance program prior to employment with Shell shall be included in Shell's annual program. - Once an employee has been included in an asbestos medical surveillance program, the surveillance should be continued throughout the term of his or her Shell employment. Upon leaving Shell, each employee who has been included in an asbestos medical surveillance program shall be administered according to the Shell pre-separation counseling cr extended medical surveillance program policy (post-retirement physical examinations), whichever is appropriate. * The phrase "reasonably predictable and repeated basis" is currently interpreted for present job assignments, to mean at least eight hours of exposure per calendar quarter. For exposures that have occurred in past job assignments, "repeated" shall mean at least two calendar quarters. It should be recognized that these exposure criteria represent an administrative judgment, since minimal exposure levels required to cause disease are not known with certainty at this time. This administrative judgment may be revised in the future, with the concurrence of Corporate Medical, Toxicology, Safety and Industrial Hygiene and the affected functional manaoement.

Inhalation may cause lung cancer, mesothelioma, and other diseases such as asbestosis and pleural lesions. - Generally, the incidence of cancer and asbestosis among occupationally exposed persons increases with increasing intensity of exposure; the * inhalation of high concentrations for short durations may be as harmful as prolonged exposure to low concentrations. - From all available evidence, the period between first exposure to asbestos and death from lung cancer appears to be related to intensity of exposure. A latency period approximating fifteen years is probably the minimum for asbestos-related lung cancer. -- - Tobacco smoking increases the incidence of lung cancer and complicates' asbestosis among asbestos workers. Regulatory Background - Permissible exposure limits to airborne concentrations of asbestos fibers are defined by OSHA standards (29 CFR 1910.1001) as follows: a) Permissible exposure level -- "The 3 hour time-weighted average airborne concentrations of asbestos fibers to which any employee may be exposed shall not exceed two fibers, longer than 5 micrometers, per cubic centimeter of air..." b) Ceiling concentration -- "No employee shall be exposed at any time to airborne concentrations of asbestos fibers.in excess of 10 fibers, longer than 5 micrometers, per cubic centimeter of air..." - Per OSHA Program Directive #300-16 dated October 11, 1978, titled, "Minimum Airborne Fiber Concentration For Initiating and Continuing Asbestos Medical Examinations", the term "...exposed to airborne concentrations of asbestos fibers..." is administratively interpreted to mean "...exposed to a minimum of 0.1 asbestos fibers longer than 5 micrometers per cubic centimeter of air..." on a time weighted average basis. Shell Concerns - Surveys now indicate that in addition to "insulators" who are currently included in our' asbestos medical surveillance program, other employees such as pipefitters, riggers, etc. may also be exposed to asbestos as a result of their work activity. Our current medical surveillance program does not satisfactorily address the question of past exposure to asbestos. ABS-007112 LAM 023930 2 Available exposure data indicate that exposures during :rip out' or removal of asbestos-containing insulation may exceed 0.1 fibers per cubic centimeter. Accordingly, all employees, regardless of job title, whose work assignments now or in the past, would involve 'rip out' or removal cf asbestos-containing insulation, on a reasonably predictable and repeated basis, are to be included in an annual asbestos medical surveillance program. The term "reasonably predictable and repeated basis" is interpreted for past job assignments to mean at least eight hours of exposure in two calendar quarters. A copy of the program is included in Attachment I. The information provided by the employees indicates that there are some jobs which meet the above exposure criteria. These jobs include the roustabout, pipeliner, and mechanic. All employees assigned as a roust about or mechanic prior to 1984 or as a pipeliner prior to 1972 for a period of six months or more and who are currently working for SPLC or Shell Oil Company or one of its subsidiaries should be identified and included in the Shell Asbestos Medical Surveillance Program. Use of asbestos-containing materials was discontinued in 1972. However, roust abouts and mechanics potentially were involved in rip out of asbestoscontaining insulation in the pump stations up until 1984 at which time an asbestos abatement project was completed and contractors began handling asbestos removal projects. A description of the past exposures based on the employee interviews is included in Attachment II. CAS8904004 LAM 023931 ABS-007113 3 Implementation: Suggested Action PI an/Guidel fries - Evaluate exposures and identify employees whose job assignments, new or in the past, result in exposure to asbestos as defined in the Policy, and include them in the annual asbestos medical surveillance program. - Due to the varied nature of potential exposure throughout Shell, there may be specific employee concerns that will require the prudent, balanced judgements of both functional management and the Head Office Corporate Medical and Safety and Industrial Hygiene Department. Full consultation, prior to arriving at a decision, is encouraged in these cases. - For the above Identified employees, provide improved-training and information to emphasize: a) Synergism of asbestos and smoking, b) Need for participation in medical examination programs. - Review current operating procedures for reducing or eliminating physical contact between asbestos fibers and employees. LANI 023932 ABS-007114 ATTACHMENT II PAST EXPOSURES TO ASBESTOS IN SHELL PIPE LINE CORPORATION WEST COAST DIVISION BASED ON EMPLOYEE INTERVIEWS The employees indicated that prior to 1972 a pipeliner's job tasks included mixing asbestos paste to use as packing to seal off the pipeline when work was "being done. Estimates of the frequency of this activity ranged from two to twelve times per year. Until 1984, roustabouts were involved in the repair of deteriorating asbestos-containing insulation around steam piping and equipment in the pump stations. Prior to 1972, this repair work involved removing the remaining insulation from the deteriorating area, mixing an_ asbestos paste, and applying the paste to the area using a trowel. Cheesecloth, or similar material, was used to reinforce the paste. The finished area was then painted. In some cases, sections of pre-formed asbestoscontaining pipe insulation was used. This was cut to size using a saw. Respiratory protective equipment was not generally used. Clean-up of the area was done using dry sweeping. Air hoses were sometimes used to clean dust off of clothing. The asbestos paste was prepared by pouring dry asbestos material from a bag into an open container. Examples of the types of containers used included a five gallon bucket and half a 55 gallon drum. Water was added to the container and mixed in with the asbestos by hand to form the paste. Indications were that this was a considerably dusty task. Respirator protection was not generally worn. Based on known exposure concentrations for other tasks involving asbestos materials, exposures while preparing a paste in this manner probably exceeded the 0.1 fiber/cc 8-hour TWA. Repair of deteriorating insulation was generally done on an as-needed basis. Employee estimates of the frequency of the activity ranged from two to six times per year. A mechanic indicated he was required to remove insulation around equipment in the pump stations in order to have access for making repairs. After repairs were made, he would then be involved in replacing the insulation. Estimates were that this activity took place about once per month. Use of asbestos was discontinued within SPLC-WCD in 1972. Asbestos materials for insulation were replaced with fiberglass. A dry ice and mud pack were substituted for sealing pipelines. Asbestos insulation remains in the pump stations. An abatement project was done in the pump station in 1984. The project included some removal and encapsulation of the remaining asbestos-containing insulation. Since the abatement project in 1984, asbestos-containing insulation is handled by contractors. However, CAS8904004 ABS-007115 LAM 023933 during the period between 1972 and 1984, mechanics and roustabouts ripped out asbestos-containing insulation is order to make equipment repairs or repair insulation.
