PLAINTIFF'S EXHIBIT SM-.12 (REV. 5-78) Shell Oil Company Interoffice Memorandum APRIL 2, 1986 FROM: MANAGER, HEALTH & SAFETY, MANUFACTURING & TECHNICAL TO: SEE ATTACHED DISTRIBUTION LIST SUBJECT: HS&E PROCEDURE FOR INDUSTRIAL HYGIENE MONITORING 185-135 Each manufacturing location has been conducting industrial hygiene monitoring for a number of years. During that period, we have used the monitoring results in a variety of ways which has tended to increase the demands and requirements on the data. At the same time, we have gained knowledge and experience in managing these programs to yield the desired results. We believe it is timely to organize what we have learned and developed into a common set of principles and practices which locations and Head Office can use in the administration of I.H. monitoring programs. A joint H.O. and location task force was formed for this purpose and has been working since early last year. The task force has completed a draft in the form of an HS&E Procedure (definition attached). A copy of the draft HS&E Procedure for Industrial Hygiene Monitoring is attached for your review. An earlier, rough draft was reviewed by locations and H.O. I.H. personnel in May-June 1985. Comments from that review have been incorporated in this redraft. We delayed reissuing until now because we have been studying the possible use of a Du Pont program called LOGAN which provides both data analysis and monitoring strategy. Although the program remains of interest, Du Pont is not yet ready to offer the program for general use. We are therefore proceeding with our own work-product. Included in this procedure is a material sampling priority (Attachment I). This applies only to this procedure and has not been designed for other uses or purposes. Please review the attachment for the materials at your location, and provide feedback regarding the prioritization of specific substances. Please provide any comments directly to the task force leader, A. F. Schmit, HS&E, S&IH, IH Services. We would appreciate your comments by April 18, 1986. ____________ EMVIMMENIAl/IND.

Introduction Industrial hygiene monitoring has been routinely conducted at Shell locations to measure chemical, noise, heat, and radiation exposures. The monitoring typically involves personal sampling of the potentially exposed employees but may also include area and source air sampling as well. The monitoring is conducted for one or more of the following reasons. A. To comply with monitoring.requirements in OSHA Health Standards (Asbestos, Ethylene Oxide, Vinyl Chloride, etc.). B. To evaluate compliance with OSHA Permissible Exposure Limits (PELs). C. To evaluate compliance with Shell Internal Standards (SISs). D. In support of Shell Medical Surveillance Programs (Benzene, Asbestos, etc.). E. To investigate special concerns such as: 1. Employees with recognized health effects 2. Medical concerns 3. Employee Complaints 4. Toxicology interests 5. Regulatory changes and requests for information F. To evaluate the effect of an engineering or procedural change on exposure level. G. In response to an emergency (spill, leak, etc.). H. In support of epidemiology studies. Most existing OSHA Standards (29 CFR 1910.1000) merely specify a PEL above which employees should not be exposed. There are no formal monitoring requirements for the approximately 400 chemicals in this category. II. Purpose Initially industrial hygiene monitoring was conducted to evaluate compliance with allowable exposure limits (i.e., PELs, SISs) and to maintain surveillance through periodic monitoring. While this basic purpose remains, the demands on our industrial hygiene monitoring program have expanded. The monitoring data has been used increasingly to arrive at decisions regarding capital expenditures for exposure control, in submissions to trade organizations and Federal agencies to influence regulatory activity, and for in-house risk assessments to name a few of the major uses. Because of the CAD8606301 LAM 000751 DPMC-16453 2 significant decisions that rely on monitoring data, it is essential to continue emphasis and quality in our programs. For these reasons, a procedure consisting of basic principles and direction in the conduct of I.H. monitoring and evaluation of I.H. monitoring data has been developed. The procedure addresses: A. How many samples are needed to make a decision? B. How should the data be evaluated? C. What is the right amount of repeat or periodic monitoring? The procedure provides a methodology for conducting and interpreting I.H. monitoring. It is based largely on our experiences and judgements and makes use of limited statistical analyses. Its development also included extensive review of published sampling strategies and statistical workups by NIOSH, OSHA, academia, and industry. Where practical and beneficial, information and methods from these sources were incorporated. Since there is continuing research and study on the subject of I.H. sampling strategy, the procedure will be periodically reviewed for change and improvements. The OSHA sampling strategy in many of its health standards is based on exceeding the PEL or an action level (usually one-half of the PEL). This procedure makes use of this concept, but more fully defines the minimum sampling requirements to improve the probability of correctly judging compliance. Our goal is to make accurate decisions with the minimum required amount of data. For the purposes of evaluating monitoring data, this procedure assumes substantial compliance is achieved when exposures are at or below the OSHA PEL or Shell Internal Standard at least 95% of the time. This determination is included in the definition of the Shell Internal Standard and it is also the criteria NIOSH has previously recommended. The monitoring strategy in this procedure assumes the industrial hygienist and/or industrial hygiene technician uses his and/or her best judgement in accounting for variables such as weather, seasonal changes, process upsets, differences in workshifts, etc. The following procedures are considered as minimums, and it is anticipated additional samples may be required to evaluate numerous variables which may exist, or in some circumstances to comply with specific OSHA Health Standards. III. Initial Monitoring Strategy If industrial hygiene monitoring has not previously been conducted or if significant changes in the work place or work practices have occurred and previous data may no longer be representative, then the following steps are appropriate. A. Qualitative Assessment LAM 000752 1. CAD8606301 Identify jobs (JEPs) with the potential chemical and/or physical agent exposure. DPMC-16454 3 2. Assess relative exposure potential for each JEP (highest to lowest) B. Quantitative Assessment Industrial hygiene monitoring is typically conducted on a job (JEP) basis. That is, the monitoring or sampling data is considered representative of the job's exposures. Therefore the number of samples collected must be adequate to take into account the day-to-day and shift-to-shift variability of exposures in the job and the variability between individuals when more than one work the job. For this reason a number of samples is usually required for initial evaluation. The following tables recommend the minimum number of samples per JEP, and the minimum number of individuals and shifts to be sampled. The recommended minimum increases with the number of individuals working in the job. Since the following recommendations are minimums, judgment should be used in collecting more samples if the JEP has significant work task variation from day-to-day and/or shift-to-shift. Since nearly all JEPs may be described as being either rotating or fixed shifts, separate tables for each have been developed. TABLE 1 Minimum Number of Samples (TWA) to be Collected 1. Fixed Shifts (employees generally work same shift each day, i.e., five, 8-hour days or nights) Number Employees per JEP 1-2 3-5 6-10 11+ Percent Employees to be Sampled 100 at least 50 at least 33 approx. 25 # Shifts to be Sampled1'2 3-5 3-5 4-5 4-5 Rotating Shifts Min. # Samples per JEP 5-6 6-8 8-12 12 LAM 000753 Number Employees per shift per JEP 1-2 3-4 Number Employees per JEP3 4-8 12 - 16 Percent Employees to be sampled at least 50 at least 25 Min. # Samples per JEP1'4 6-9 9-12 1 Should include day and night shifts if there are differences in exposure potential between shifts. 2 Should consider sampling at higher range of shifts with few employees per shift. 3 Assumes four employees required to cover job with one employee per shift, rotating shifts, 24 hours per day, seven days per week. 4 Assumes % of employees (from preceding column) who can work the JEP are sampled 3-5 shifts each. CAD8606301 nPMf-i p,a^ 4 The following examples illustrate the use of these tables. Example 1: Assume 4 painters work straight days (fixed shifts), and solvent exposure levels need to be determined. Table 1 recommends sampling at least 2 of the 4 painters (50%) for 3-5 different workdays. This would result in a minimum of 6 samples. To improve the representativeness of the data, consider dividing the 6 samples among all 4 painters or as many of them as possible. Also, the 6 samples need not be collected just on 2 painters for each of 3 days. The sampling could be spread over more than 3 days and possibly improve the representativeness of the data. Example 2; Assume a Dockman works rotating 8-hour shifts round the clock each day of the year and benzene exposure levels need to be determined. There are 3 Dockmen working on any one shift, with a total of 12. The Dockmen load one barge of benzene per week. According to Table 1, at least 9 samples should be collected. They should be collected on as many different dockmen as possible but on no less than 3 (25% of 12) different dockmen. It may take several weeks to complete sampling for the initial monitoring since only 1 benzene barge is loaded per week. IV. Analysis of Initial Monitoring Results The minimum number of samples specified in Section III are necessary in order to perform the following statistical test and screen of the data. The purpose of the statistical test is to screen the initial results into data sets which clearly fall below the allowable exposure limit* (AEL) or which require more samples to determine compliance or non-compliance. For those data sets clearly below the AEL, an appropriate frequency of periodic monitoring is established based on relative exposure to the AEL and the potential hazard of the material. For example, the greater the health hazard or the closer the data are to the AEL, more frequent follow-up monitoring is indicated for that JEP. The statistical test consists of comparing the 80% upper confidence limit of the geometric mean of the data to the AEL. This parameter was selected after examining numerous existing data sets. It was found to be a relatively reliable indicator for initial compliance screening when used in the following manner. TABLE 2 80% Upper Confidence Limit of the Geometric Mean1 > AEL > .5 x AEL but ^ AEL > .1 x AEL but ^ .5 x AEL ^ .1 x AEL Category D B A LAM 000754 *May be the PEL, TLV, SIS, or other exposure limit for which a compliance determination is necessary. CAD8606301 DPMC-16456 5 The corresponding actions for each of the categories are as follows2: TABLE 3 Action______________________________ Category Materials of Priority I3 Materials of Priority II3 A Repeat initial monitoring Repeat initial monitoring biennially (lx/2 yr) if there are significant changes in workplace/ work practices B Repeat initial monitoring annually Repeat initial monitoring biennially (lx/2 yr) C Collect minimum of 20 TWA samples within three months and plot on cumulative frequency distribution graph per Section V. D Collect minimum of 20 TWA samples within one month and plot on cumulative frequency distribution graph per Section V. 1 80% upper confidence limit of the geometric mean can be calculated as follows: 80% UCL = x + .842 sTT^"(calculate using log transformed data, then convert) This calculation is also available in Stat-Graph. 2 If any sample equals or exceeds the AEL, the recommending sampling strategy should move up one category, e.g., B to C. 3 See Attachment I V. Analysis of Expanded Monitoring Results This step in the procedure should be applied when sufficient data, initial and routine monitoring, has been collected to ascertain both compliance and non-compliance with the AEL and the appropriate frequency of periodic monitoring. This step may also be useful in analyzing data in an on-going periodic monitoring program for trend analysis, analyzing the impact of a change in the AEL, reestablishing a suitable periodic monitoring frequency, etc. The additional data available at this step permits the use of the cumulative frequency distribution method to determine directly whether JEP exposures are in substantial compliance (i.e., 95% of the monitoring results are at or below the AEL). The cumulative frequency plot is illustrated below and the method is available on Stat-Graph. An example of a Stat-Graph Plot is included as Attachment II. Cumulative Frequency Distribition % Exposures ^ Stated Value LAM 000755 CAD8606301 DPMH-IR4R7 6 TEe results of this analysis should be compared to Table 4 to determine appropriate periodic monitoring frequency. The monitoring frequency is a function of 2 factors: 1) the exposure levels relative to the AEL; and 2) the health hazard of the material. The monitoring frequency is increased as the exposure levels approach the AEL and as the potential health hazard increases. The exception is the situation where we are not in substantial compliance (i.e. 95% level of cumulative frequency distribution exceeds AEL) and further engineering controls and/or work practices to reduce exposure are infeasible. In this case, suggested monitoring is less frequent with more emphasis placed on compliance using personal protective equipment (PPE). In some cases, the recommended periodic monitoring frequency may not provide sufficient data to permit statistical analysis for one or more years. However, these cases are limited to situations and JEPs which are already under relatively good control and for which exceeding the AEL is unlikely.

In general, the more hazardous the material, the greater the need for industrial hygiene monitoring. For example, a known human carcinogen will likely require more frequent industrial hygiene monitoring than a nuisance dust. To take into account the significance of hazard, two sampling priorities, I and II, are established. They are defined as follows: Priority I Materials which have the potential to produce irreversible acute or chronic health effects, e.g., carcinogens, reproductive hazards, neurotoxins, hepatoxins, fibrosis-producing dusts, etc. Examples: Benzene, Vinyl Chloride, Epichlorohydrin, Oxitol (2-ethoxyethanol), Inorganic and Organic Lead, Ethylene Oxide, Ethylene Dibromide, Asbestos, Crystalline Silica, Hydrogen Sulfide, Chlorine, all materials included in the Protection of the Embryo/Fetus Policy. Priority II Materials which may produce only reversible acute or chronic health effects including typically irritants and nuisance dusts. Examples: Acetone, Isopropyl Alcohol, VM&P Naphtha. Materials for which there is industrial hygiene monitoring data in the Health Surveillance System have been reviewed and categorized as follows: CAD8606301 LAM 000757 DPMC-16459 ATTACHMENT I PAGE 2 OF 10 CONTAMINANT CODES (ALPHABETICALLY) - REVISED 4/86 THESE-ARE THE CONTAMINANT CODES TO BE USED ON IH SAMPLING FORMS.

If the sample time is less than this minimum but zero exposure time for the unsampled period can be and is documented, then the sample can be considered a TWA. The "TWA Determination Section" of the Industrial Hygiene Sample Form should be completed according to previously issued instructions. If a sample is intended to be a TWA, but the minimum sample time as defined above is not achieved, the "TWA Determination Section" of the Sample Form should be completed as "TWA Cannot Be Calculated". Peak - Samples represent specific short-term tasks ranging from 1-30 minutes in duration. When feasible, try to attain a sample time of 15 minutes of duration of the task, not to exceed 30 minutes. Task - Samples represent specific tasks exceeding 30 minutes duration, but not representative of the TWA exposure. Examples of such tasks would be loading/unloading of a tank car or truck, gauging, or decontaminating a pump for maintenance. PEAK/TASK SAMPLE FREQUENCY Peak samples (or task if duration exceeds 30 minutes) should be taken in conjunction with TWA sampling during initial determination of high concern chemicals. This sampling should be done regardless of the OSHA peak/ceiling or ACGIH STEL status for the chemical being monitored. The purpose of this monitoring is to further characterize the exposure profile of the job. Subsequent samples should be taken if initial TWA determination results in Categories B, C or D. 0FFSHIFT SAMPLING Jobs with multiple or rotating shifts should be evaluated for differences in job activities between shifts. It is normally most practical to sample on day shifts and this is appropriate where activities on all shifts are virtually the same. However, if exposure potential varies with the shift, it will probably be necessary to consider alternate means of collecting representative data. CAD8606301 LAM 000768 DPMC-16470 ATTACHMENT IV MULTIPLE EXPOSURES WITH POTENTIALLY ADDITIVE HEALTH EFFECTS Where multiple exposures occur to materials which act upon the same organ system, e.g., they are irritants, narcotic, hepatotoxic, etc., their combined effect, rather than that of either individually, should be considered as additive. In these situations, the initial quantitative determination should be analyzed by adding the 80% upper confidence limits about the mean for the additive materials, and then identifying the sum as Category A, B, C or D by the standard criteria.; If the sum falls into Categories C or D, then additional monitoring should be conducted for each of the additive materials. After the additional monitoring is conducted, the results should be analyzed by adding the 95% level of the Cumulative Frequency Distribution for each of the additive materials. The sum should then be compared to the standard criteria for determination of periodic monitoring frequency. Each of the additive materials should be monitored according to this frequency. Examples: Assume that for one JEP, both Allyl Chloride (AC) and Epichlorohydrin (ECH) are monitored. These materials have potentially additive toxic effects and; therefore, the combination of the exposures should be considered in the evaluation of industrial hygiene monitoring data, and in the determination of sampling strategy. The following cases represent examples of applying the standard criteria to the combination of exposures: Case 1 The initial quantitative survey showed - - The 80% UCL of mean for ECH <0.1 SIS (Shell Internal Standard) - The 80% UCL of mean for AC < 0.1 PEL - Since the sum of the 80% UCLs does not clearly exceed 0.1 PEL, this would remain Category A with a reassessment in two years because of the Material Sampling Priority (I) of the two materials. Case 2 The initial quantitative survey showed - - The 80% UCL of mean for ECH < 0.1 SIS LAM 000769 - The 80% UCL of mean for AC = 0.4 PEL - In this case, the sum of the 80% UCLs is between 0.4 and 0.5 PEL, placing the JEP in Category B. As a result, the initial quantitative survey should be repeated in one year. CAD8606301 DPMC-16471 2 Case 3 The initial quantitative survey showed - - The 80% UCL of mean for ECH = 0.2 SIS - The 80% UCL of mean for AC = 0.3 PEL - In this case, the sum of the 80% UCLs is 0.5 PEL, placing the JEP in Category C. Additional samples should be collected for both ECH and AC. After 20 samples of each are obtained, assume the following results are obtained: 95% cumulative frequency level for ECH = 0.4 SIS 95% cumulative frequency level for AC = 0.4 PEL Since the sum of the 95% cumulative frequency levels is 0.8 PEL and the -few Material Sampling Priority is I, the JEP should be periodically monitored two times per quarter for each material.

Exposure monitoring during these activities on operators, pipefitters, boilermakers and others reflects how well the existing equipment and established procedures control exposure. After an initial evaluation, monitoring should be considered on subsequent shutdowns if there are changes in the procedures and/or to verify adequacy of work procedures. The frequency of monitoring turnarounds for verification of procedures will depend on the hazardous properties of the materials and the potential for exposure. The following table illustrates an example. UNIT TURNAROUNDS1 Material Sampling Priority2 Representative exposure data been collected within 3 years? Minimum frequency for conducting3 Extent of each survey Bring Bring Down4 Up5 I Yes IX/3 turnarounds X I No Alternate X each turnaround II Yes Alternate XX each turnaround II No Each turnaround X X New or modified N/A Initial then N/A X select 1-4 LAM 000773 1 Applies to major turnaround activity, not necessarily partial shutdowns 2 See "Attachment I 3 Minimum time between monitoring turnarounds is three years 4 Consider monitoring operators during the decontamination and purging of unit for the turnaround and both operators and maintenance during initial opening of process equipment. After process equipment has been opened, consider monitoring of craftsmen on a task basis, e.g., welding. 5 Consider monitoring operators as unit starts up and returns to normal operation.
