ACCEPT the attached report from the Hazardous Materials Commission and the Public and Environmental Health Advisory Board. 2. CONSIDER the recommendations made in this report concerning proposed changes to the Industrial Safety Ordinance. BACKGROUND: s� At the December 4, 2001 meeting, the Board of Supervisors asked the Hazardous Materials Commission and the Public and Environmental Health Advisory Board to review and provide recommendations on four proposed amendments to the County's Industrial Safety Ordinance (ISO). Two of these proposed amendments dealt with the role of Inherently Safer Systems in conducting Process Hazard Analyses at facilities. The third proposed amendment recommended changes to the contractor training requirements contained in the ordinance. The fourth proposed amendment suggested incorporating the elements of a specific accident prevention program, the Triangle of Prevention program, into the ordinance. The Hazardous Materials Commission had previously held a`retreat on March 22, 2001 to plan their priorities for the upcoming year. One of the priorities that emerged from that planning process was to undertake a comprehensive review of the ISO. In response to the December 4, 2001 referral from the Board, the Hazardous Materials',Commission decided to review and develop recommendations for these four new proposed amendments as part of their comprehensive review of the ISO.

The PHA's and PHA revalidatons' should be conducted in conformance with Section 2760.2 of the CaIARP program regulations and.. Section 7.3 of the Contra Costa County CaIARP Program Guidance Document except in assessing whether seismic eventsmust be considered. Seismic events must be considered (i,e., a veisrnic assessment must be conducted) if the covered process (as defined in Section 450-8.014(a)of County Ordinance Code Chapter 450-8)contains a regulated substance (as'defined in Section 2735.3(n)of the CalARP'program regulations) and the distance to the nearest public receptor for a worst case release scenario'is within the distance to the toxic or flammable endpoint..2 The seismic assessment should be conducted in accordance with Section 7.3.4 and Appendix B of the Contra Costa County CaIARP Program Guidance Document. Additionally,County Ordinance Cade Chapter 450-8,Section"450-8'016(D)requires the following for conducting PHA's. D.1 INHERENTLY SAFER SYSTEMS The intent of the Inherently Safer Systems requirements is that each stationary source,using good engineering practices and sound engineering judgment will incorporate the highest level of reliable hazard reduction to the greatest extent feasible, to prevent Major Chemical Accidents and Releases. "Inherently Safer Systems(ISS)means Inherently Safer Design;Strategies as discussed in the 1996 Centerfor Chemical Process Safety Publication "Inherently Safer Chemical Processes„ and means feasible alternative equipment, processes, materials, lay-outs,, and procedures meant to eliminate, minimize, or reduce the risk of a Major Chemical Accident or Release by modifying'a process rather than adding external layers of protection. Examples include, but are not limited to, substitution of materials with lower vapor pressure,'lower flammability,or lower toxicity; isolation of hazardous processes;and use of processes which operate at lower temperatures and/or pressures." County Ordinance Code Chapter,450-8 §450-8.014(g) "For all covered processes, the stationary'source shall consider the use of inherently safer systems in the development and analysis of mitigation items resulting from a process hazard analysis and in the design and review of new processes and facilities." County Ordinance Code Chapter 450-8 as amended by County Ordinance 2000-20, Section 450-8.016(D)(3). The term inherently safer implies that the process is safer because of its very nature and not because equipment has been added to make it safer.3 1996 Center for Chemical Process Safety Publication Inherently'Safer Chemical Processes has defined four categories for risk reduction: r As specified in California Cade of Regulations,Title 19,Chapter 4.5,Section 2750.3 2 As specified in California Code of Regulations,Title 19,Chapter 4.5,Section 2750.2(x) 3 Process Plants: A Handbook for Safer Design, 1998,Trevor Kletz D_1 Section I3 }late:September 12,2002 • Inherent-Eliminating the hazard by using materials and process conditions which are nonhazardous; e.g., substituting water for a flammable solvent. • Passive - Minimizing the hazard by process and equipment design features which reduce either the frequency or consequence of the hazard without the active functioning of any device; e.g., the use of equipment'rated for higher pressure. • Active'--Using controls,safety interlocks,and emergency shutdown systems to detect and correct process deviations;e.g., a pump that is shut off by a high level switch in the downstream tank when the'tank is 90% full. These'..systems are commonly referred to as engineering,controls. • Procedural - Using operating ;,procedures, administrative checks, emergency response,and other management approaches to prevent incidents,or to minimize the effects of an incident;e.g.,hot-work procedures and permits. These approaches are commonly referred to as administrative controls. "Risk control strategies in the first two categories, inherent and passive, are more reliable because they depend on the physical and chemical properties of the system rather than the successful operation of instruments, devices,procedures, and people. 4 The inherent and passive categories should be implemented when feasible for new processes and facilities and used during the review of Inherently S afer Systems for existing processes if these processes could cause incidents that that could result in a Major Chemical Accident or Release. The final two categories do require the successful operation of instruments,devices,procedures, and people. The concepts that are discussed in the COPS book,Inherently Safer Chemical Processes,A Life Cycle Ap' rp oath,for looking at active and procedural applications of risk reduction, should be used in developing recommendations'and mitigations from process hazard analyses along with the inherent and passive categories. This is goad risk reduction. These concepts should also be used in the review and application of human'factors for process hazard analysis of new and existing processes: Approaches to consider Inherently Safer Systems include the following4: • Minimization — Use smaller quantities of hazardous substances (also called Intensification) • Substitute—Replace a material with a less hazardous substance • Moderate--Use less hazardous conditions, a,less hazardous form of a material,or> facilities that minimize the impact of release of hazardous`material or energy(also called Attenuation or Limitation of Effects) • "Simplify Design facilities that eliminate unnecessary complexity and make operating errors less likely,and that are forgiving of errors that are made(also called Error Tolerance) The following guidance on the review of Inherently Safer Systems is broken dawn into seven separate sections. The first section addresses new covered'processes, the second section addresses existing processes;the third section addresses mitigations resulting from Process Hazard Analysis (PHA); the fourth section defines feasibility; the fifth section addresses 4 CCPS,Inherently Safer Chemical Processes.A Life Cycle Approach, 1996 D-2 Section I) Date: Se teber 12,2002 recommendations from process hazard analyses;the sixth section addresses Inherently Safer System Deports;and the seventh section contains definitions.: As discussed in the fallowing sections,the ISS analyses must be performed for situations where a major chemical accident or release could reasonably occu References on the approaches to Inherently Safer Systems to consider are listed at the enol of this section D.1.1 Inherently Safer Systems Analysis for New Covered Processes' The Industrial Safety Ordinance requires a stationary source to consider Inherently Safer Systems " . . in the design and review of new processes and facilities." (§450- 8.016(D)(3)). This section describes the different phases in the development of a project that an Inherently Safer Systems analysis should be used. Inherently Safer Systems should be reviewed early in the development phase of a new covered process and then reviewed throughout the different project design phases. The objectives for an inherent safety review are to employ synergistic teams to • Understand the hazards • Find ways to reduce or eliminate the hazards Thefirst major objective for the inherent safety review is the development of a good understanding of the hazards involved in the process Reducing and eliminating hazards and 'their associated risks is the second major objective. Applying inherent safety principles early in the productlprvicess development: effort provides the greatest opportunity to achieve the objectives of the inherent safety review processfor the project at hand, The stationary source should use a review process for new processes that includes an Inherently Safer Systems review at different phases of the design process such as the following phases when applicable: • During the chemistry forming(synthesis)phase for product/process research and development to focus on the chemistry and process 5 Process Hazard Analysis methods determine the risk of a deviation or potential incident. The risk determination is based on a combination of the hazard(severity)of the potential incident and likelihood(probability)of an incident occurring. If the potential hazard(severity)of consequence of a deviation meets the definition of a Major Chemical Accident or Release an ISS Analysis should be done for those that could reasonably occur. 6 Composition of the review teams will vary at different phases of the development cycle of the project and with the; nature of the process. In product development and design scope,the team may comprise of chemist,process design engineers,industrial hygienist,safety engineer,environmental,and control engineer etc. In the hazard and operations review phase,the team may include operations and maintenance personnel as well. A stationary source may choose not to use an ISS review team at a particular phase. If this does occur,the stationary source should document the reasons for not using a;team for performing an ISS review during this particular phase. A multi-disciplined'group should be used throughout the various phases of development.implementation,and operation. 7 CCPS,Inherently Safer Chemical Processes A Life Cycle Approach, 1996 D-3 Section D Date:September 12 2002 • During thefacilities design scoping and development prior to completion of the design basis to focus on equipment and configuration • During the basic design',phase of the project CCHS understands that for different stationary sources and different;projects that the above phases,timing and sequencing,may not always be applicable. For some projects, the chemistry may complete and the chemistry-forming phase is not applicable. For some stationary sources` it may be more appropriate to do inherently safer system analyses at phases that are not quite the same as described above, but is at the same approximate timing in a''project development and design phases. The intent is that a stationary source' conducts inherently safer system analysis early in the project development and throughout the various phases of the design. Stationary Sources should recognize that the earlierin a project development and design the easier and less costly it is to make a'change to implement Inherently Safer Systems. D.1.11 Applying Inherently Safer Systems Review—Chemistry-Farming Phase Inherently Safer Systems should be evaluated early in the assessment of the project. When applicable, this assessment''should be done in the chemistry-forming phase during the product and process research and development. A team with diverse background would best perform the assessment. The team assessment should address such topics as: • Understanding of the hazards • Choice of best route to produce a'given chemical or product • Process improvement o Reactor types and conditions o Intermediate storage optimization o Waste'minimization • Identify requirements for additional information Some of the information that may need to be available'prior to this review includes the followings: • Simplified process flow diagrams o Include alternative processes • Defined chemical reactions o Desired and undesired o' Develop potential for runaway reactions/decompositions • A list of all chemicals and materials employed o Develop compatibility matrix a' Include air, water, rust, etc. • Defined'physical,chemical,'and toxic properties sEarly review often will not have all of the information listed. Do not wait to complete the reviews before all of this information is developed. The later reviews should cover the information that was not available in the earlier reviews. D-4 Section D Date: September 12,2002 • Defined process conditions(pressure,temperature,etc.) • Estimated quantities used in each process system (tanks, reactors, etc.) - o Estimate quantities of wastes/emissions The review team should examine the following questions: • Can safer chemicals be used? • Can quantities be reduced? • is the overall risk increased by implementing an ISS? • Can waste be reduced? (Regenerable catalyst or recyclable.) • What additional information is required'? (Toxicology information,heats of reaction, or reactive,chemicals data.) Documentation that should be kept for this phase of the project, when applicable, includes, but not limited to: • How the decision was made to perform an Inherently Safer Systems Review at this phase • How the assessment was performed • The assessment team leader, including the relevant experience of the team leader • The makeup of the assessment team by discipline, experience, and name of the participants • The information that was prepared and available during the assessment • How the hazards were understood, including flammability, toxicity, and reactivity • The different routes to produce a given chemical or product and how the best route was determined, including the criteria and method used for this determination • How process improvements were reviewed and the determination of the process that was determined to be the inherently safest process • The answers to such questions as those listed above • The identification of requirements for additional information D-5 Section D Date:September 12,2002 D.1.1.2 Applying Inherently Safer Systems Review—Facilities Design Scoping and Development Inherently safer system should then be evaluated during the design-scoping phase of the project when applicable. The evaluation should concentrate on the following: • Minimizing equipment • Reducing inventories • Simplifying the process • Reducing wastes • Moderating process conditions The preliminary information that should be available prior to the development phase of the project ISS review may include the following.' • Process flow diagram or simplified process flow diagram • Material and Energy Balance • Defined chemical reactions • Defined physical,chemical, and toxic properties During the review the team should examine questions such as • Previously unanswered questions • Can potential releases be reduced via lower temperatures or pressures, or elimination of equipment • Can quantities be reduced? • Can waste be reduced? (Regenerable or recyclable catalyst.) • Can different equipment be used resulting in safer conditions? Documentation that should be Dept for this phase of the project includes, but not limited to: • How the decision was made to do an Inherently Safer Systems Review at this phase • How the assessment was performed • The assessment team leader, including the relevant experience of the team leader • The makeup of the assessment team by discipline, experience, and name of participants • The information that;was prepared and available during the assessment • The process used to determine that the equipment sizes are minimized and the results of this determination • The process used to determine the minimum inventories 'needed and .the results of this determination D-6 Section D Date: September l2,2002 • The process used to simplify the covered process', if applicable, and the results of this process • The process used to reduce the waste made from the project and the results of the determination • How the moderation of the process was done-the checklist in Attachment A could be used in this determination • The answers to such questions as those listed above • The identification of requirements for additional information D.1.1.3 Applying Inherently Safer Systems Review—During the Basic Design of the Project During this assessment phase,use of inherently safer systems should be reviewed and documented. This may be achieved using :a checklist that incorporates ISS considerations such as those listed in Attachment A. Another method that may be used is the incorporation of additional parameters and guidewords such as those used in a Hurd and Operability Study. An example of guidewords or parameters that could be used is shown in Attachment B. These analyses would review the covered processes for ways to eliminate or reduce hazards that are present in the covered process. Preliminary safety critical devices and procedures should be examined to determine if there is a way to eliminate the need for the device or procedure by applying;principles of inherently safer systems. The information preparedprior to the design phase of the project should include the process safety information that is required under the 'Industrial Safety Ordinance and CaIARP Program. Some of the information to be included with the process safety information is the following: • Process Flow Diagrams (PFD's) • Piping and Instrument Diagrams (P&ID's • Material and Energy Balance • Equipment specifications • Designing equipment for isolation when applicable—(P&ID's may be sufficient to address this requirement) • Preliminary safety critical procedures or guidelines • Instrumentation logic information - (P&ID's .may be sufficient to address this requirement) During the ISS Study the team should consider such questions as: • Can potential releases-,be reduced via lower temperatures or pressures, lower concentrations,elimination of equipment,by using seatless pumps,etc.? • Can quantities be reduced? • Can waste be reduced? The documentation that should be included'for the checklist analysis includes the items that are applicable from the checklist in Attachment A,what items were considered,how D-7 Section D Date;September 1 ,2002 they were considered,and the results of the consideration. For items that were applicable and not considered, document why each item was not considered. The documentation for incorporating the guidewords for inherently safer systems into a Hazard and{operability Study should be consistent with the documentation used during any Hazard and Operability Study. Other-methods for performing an Inherently'Safer Systems Analysis maybe appropriate. If another method is used, the stationary source must work with Contra Costa Health Services itt`&Wrli iniag that this method is appropriate for analyzing for inherently safer systems prior to implementation. The documentation must include the-makeup of the review team by discipline,relevant experience, and the names of the review leader and participants. D.1.2 Inherently Safer Systems Analysis for Existing Process Units The Industrial Safety Ordinance requires that stationary sources consider hazards as part of the process hazard analyses. "The process hazard analysis shall be appropriate to the complexity of the Covered Process and shall identify, evaluate, and control the hazards involved in the Coverer Process. The process hazard analysis shall address= the hazards of the process, the identification of any previous incident which had a likely potentialfor catastrophic consequences; engineering and administrative controls applicable to the hazards and their interrelationships such as appropriate application'of detection methodologies to provide early warning of releases." 'Chapter 450-$ §450-$.016(D)(1) NOTE: Inherently Safer Systems need'only be considered for scenarios where a Major Chemical Accident or Release could reasonably occur. This could include a process or parts , of a process. The stationary source needs to establish a method to make the determination of a potential occurrence of a Major Chemical Accident or Release. This could include examining each consequence of a'deviation, including the severity of each consequence. Stationary sources should perform one of the following methods to ensure that inherently safer systems (inherent and passive categories) are considered and documented for the covered,processes. An independent inherently'safer system analyses that is done in addition to a PHA9. These analyses should review the covered processes for ways to eliminate or reduce hazards that are present in the covered'process. This may be achieved by using a 9 If the stationary source decides to do an independent inherently safer systems analysis,CCHS suggests that this be donee in conjunction with the process hazard analysis,but it may be appropriate for a stationary source to perform an inherently safer systems analysis that is done at a different time than the process hazard analysis.' Either approach -meets the guidance from this document,as long as the inherently safer systems analysis is revalidated at least once every five years. D-$ Section D Date: SM !ember 12,2002 checklist (Attachment A) or guideword analysis (Attachment B)that incorporates ISS.If the stationary source decides to use some other ISS checklist or other methods to evaluate ISS,these must be approvedby CCHS prior to their use. + An inherently safer system analyses that is incorporated into the existing PHA review process. This would require that each covered'process in its entirety have an initial ISS analyses conducted. (Incorporating inherently safer systems into a revalidated process hazard analysis may not be sufficient to satisfy the initial inherently safer system review if the whole process is not evaluated.) This may be achieved using a checklist (Attachment A);or guideword (Attachment B) that incorporates ISS considerations into a Hazard and Operability Study where a Major' Chemical Accident or Release could reasonably occur. These analyses would review the covered processes for ways to eliminate or reduce hazards as well as risks that are present in the covered process. Whichever type of ISS analysis is implemented by the stationary source the following will need to be done: • The stationary source will develop and document their approach to evaluating ISS'for existing processes. Contra''Costa Health Services will review the ISS analysis method'selected to determine that the method meets the requirements of the Industrial Safety Ordinance and this guidance document. • The stationary source will document the qualifications of the team facilitator/leader and team makeup,including positions,'names,and any relevant experience or training.` •' The stationary source will document the ISS's considered as well as those implemented. Implementing only one option to address identified hazards may not be adequate to address- the greatest hazard reduction or elimination. However, it is not Necessary to implement more than one ISS if the implementation of a second ISS does not add any significant hazard reduction or has been documented as infeasible. • If the stationary`source chooses to do an independent inherently safer systems analysis,the stationary source should document the method used for the analysis, what inherently safer' systems were considered, and the results of each consideration. If the checklist for Inherently Safer Systems was used,for items that were not considered,document why those items were not considered,i.e.,not applicable or were already considered in previous consideration. • The stationary source will document for the ISS considered and not implemented, the grounds that were used to make the feasibility determination '(See D.1.4 Feasibility), D-9 Section D Date:September 12 2002 • The documentation for incorporating,the guidewords for inherently safer systems into a Hazard and Operability Study should be consistentwith the documentation used during any Hazard'and Operability Study. • For any other inherently safer system analysis, the stationary source should document the inherently safer system considered, the inherently safer system implemented, and the inherently safer systems not implemented. •' The ISS analyses should be revalidated at least once every five years. The revalidation should include and document the following: • Incorporate improvements made in method since the last review was conducted or select a new method to perform the ISS analyses. o ISS review for all changes that have been made since the last ISS analysis. o Review of all major chemical accidents or releases or potential major chemical accidents or releases that occurred at the process under review. o Review for any new and existing technologies not previously reviewed that can be incorporated that will make the process under review inherently safer. D.1.3 Process Hazard Analysis Reconunendations and Mitigations The concepts as addressed in the CCPS book Inherently Safer Chemical Processes A Life Cycle Approach for looking at all four categories of risk reduction(Inherent,Passive,Active, and Procedural)should be used in the development and mitigation of recommendations from process hazard analysis as well as for considering Human Factors.10 Chapter 4 of the COPS book Inherently Safer Chemical Processes A life Cycle Approach discusses many inherently safer system strategies that can be incorporated in the development of mitigations to address the recommendations from process hazard analysis. The stationary sources should provide guidance to personnel responsible for developing and analyzing recommendations and mitigation items resulting from the unit PHA. The guidance should include the concepts of inherently safer systems including: • The different categories of risk reductions • Moving up the different levels from procedural to active to passive to inherent levels • Approaches to apply inherently safer systems including minimization, substitution, moderation; and simplification 10 County Ordinance Code Chapter 450-8,§450-8.016(D)(3) "For all Covered Processes,:'the Stationary,Source shall consider the use of Inherently safer Systems in the development and analysis of mitigation items resulting from a process hazard analysis :"and County Ordinance Code Chapter 450-8 §450-8.015(D)(4) "Far all Covered Processes,the Stationary Source shall document the decision made to implement or not implement all process hazard analysis recommended action items and the results of recommendations for additional study.. ." D-10 Section D Date: September 12,2.042 The stationary source should document how they used the inherently safer system strategies for risk reduction in developing and analyzing mitigations to address the recommendations from a process hazard analysis. There should be sufficient detailed documentation satisfactory to CCHS and should at least include the following for the stationary sources ISS program description: •`' The facility has a'program in place to ensure that risk reduction actions taken to address PHA recommendations incorporate inherently safer systems; • The program incorporates at a minimum; the four levels of risk reductions described beginning on page D-1 of this document. • How the stationary source encourages moving up the levels from procedural to inherent in the implementation of the inherently safer system strategies. The stationary source should also document the implementation of ISS strategies and should include the following. • At least one risk reduction action was taken using inherently safer system strategy for each PHA mitigation item for scenariosthat have the potential for a Major Chemical Accident or Release: • A description of the risk reduction method selected and the inherently safer system strategy used. • Details of risk reduction mitigation considered using the inherently safer system strategy that was not implemented. • Reasons the rejected risk reduction mitigation was determined to be infeasible using the inherently safer system strategies. D. 1.4. Feasibility The Industrial Safety Ordinance requires the stationary source to select and implement ISS to the greatest extent feasible(Section 450-8.016(13)(3)). The Industrial Safety Ordinance also defines feasible . capable of being 'accomplished in a successful manner within a reasonable period of time, taking into account economic, environmental,legal,social, and technological factors. To assist in the determination of feasible, Contra Costa Health Services is using a modification of the following guidance from OSHA (Federal OSHA provided guidance for justifiably declining recommendations from incident investigations in the September 1994,OSHA.Instruction CPL 2-2.45A CH-1. These criteria have since been applied to recommendations formulated during PHA's.) and the U.S.EPA: • The analysis upon which the recommendations are based contains factual errors. • The recommendation is not necessary,'i.e.,the safeguards may be inadequate,but the consequences are operational or the consequence or severity of the scenario would not result in a Major Chemical'Accident or release. • An alternative ISS°would'provide a sufficient level of hazard reduction(NOTE: Implementing only one option to address identified hazards may not be adequate to address the greatest hazard'reduction or elimination. However, it is not necessary to implement more than one ISS if the implementation of a second ISS does not add any significant hazard'' reduction or has been documented as D-11 Section D Date:22amber 12,2002 infeasible'.} • The recommendation is in conflict with existing federal, state, or local laws. • The recommendation is in conflict with Recognized and Generally Accepted Goad Engineering Practices (R.AGAGEP). • The recommendation is economically impractical,such that the process unit can no longer be financially operated. This can include the following factors: o Capital investment o Product quality o Total direct manufacturing costs o Operability of the plant o Demolition and future clean-up and disposal cost • The recommendation would have a negative social impact such that the project. should not be implemented. Some examples of social impact include the recommendation would have a visual or noise impact on the community that is not acceptable and the recommendation would cause or increasethe traffic congestion. • The recommendation may violate a license agreement and the license agreement cannot be modified and must remain in effect. • The recommendation may decrease the hazard, but would increase'the overall` risk. • An alternative measure would provide more risk reduction than the ISS. • If the ISS' recommended is determined not to be implemented because it will create more risk,or if other modifications that are not ISS are made such that the overall risk is less than if the ISS were implemented, the stationary source will need to document how this determination was made. A qualitative risk assessmentlanalysis could be used as a basis for the risk analysis. The facility needs to document how they determined the qualitative severity and likelihood for the existing' or modified conditions and for the conditions if the ISS is implemented. If the qualitative risk analysis shows the same level of risk,then a quantitative risk'assessment/analysis should be performed to compare the risk of the existing or modified conditions to the risk if the ISS is implemented. The documentation'should''include the background information that was used to do the comparison of the existing or modified conditions to the conditions if the ISS is implemented. Another method may be used by the stationary source,such as a weighted'scoring decision matrix as shown on page 23 of CCPS book Inherently Safer Chemical Process A Life Cycle Approach, if that method is approved by Contra Costa Health Services prior to the use ofthe method. County Ordinance Code Chapter 450-8, §450-8.016(D)(3) requires the following "This documentation shall include (1) sufficient evidence to demonstrate to the County's satisfaction that implementing this inherently safer system is impractical, and (2) the reason for this conclusion." The documentation should include the applicable background information,calculations,and the reasons that an inherently safer system was not implemented. If there is any concern that the reasons for not D-12 Section D Date: September 12,2002 implementing an inherently safer system would not satisfy Contra Costa Health Services, the stationary source should consult with Contra Costa Health Services to determine if the justification is satisfactory. The stationary source should then receive in writing from Contra Costa Health Services their decision and how they came to their decision including background information, calculations, and alternatives considered. D.I.S Completion of Recommended Action Items` Stationary sources must document the decision made to implement or not implement all process hazard analysis recommended action item and the results of recommendations for additional study.This documentation must include the justification for not implementing,any recommended actions. Federal 'OSHA provided guidance for justifiably declining recommendations from incident investigations in the September 1994, OSHA Instruction CPL 2-2.45A CH-1.These criteria have since been applied to recommendations formulated during PHA's. NOTE: Additionally,CCHS encourages stationary'sources to consider the impact on surrounding communities when declining recommendations. • The analysis upon which the recommendation is based contains material factual errors • The recommendation is not necessary to protect the health and safety of the employer's own employees, or the employees of contractors • An alternative measure would provide a sufficient level of protection` • The recommendation is infeasible Cal/OSHA issued the following clarification in Part 4 of the June 1994 Process Safety Management Guidelines. "...Cal/OSHA's intent is that .an employer is required to implement the teams' findings and recommendations except to the extent that an employer can document that an alternative will be at least as effective or efficient in addressing the safety concerns that are the subject of those findings and recommendations". The stationary source must complete the recommended actions selected for implementation, including'those formulated during PHA, as follows: • All actions not requiring a process shutdown must be completed within one year after submittal of the original Safety Plan or after completion of the PHA revalidation unless the stationary source demonstrates to the satisfaction of Contra Costa Health Services that within one year is infeasible • All actions requiring a process shutdown shall be completed during the first,;regularly scheduled turnaround of the applicable',process subsequent to one year after submittal of the Safety Plan or after completion of the PHA unless the stationary source demonstrates to the satisfaction of Contra Costa Health Services that such a schedule is infeasible D-13 Section D Dater September 12,2002 ISS Study and ISS Revalidation recommendations should be resolved in a timely manner. CCHS Staff may request that the stationary source make the plans for completing these recommendations available during facility,audits. Examples of situations where the schedule may be infeasible include procuring customized equipment requiring along lead time for fabrication and delivery,complex projects requiring significant front-end engineering, facilities that require substantial time to construct, or implementing a recommended action that requires the application of a local air district permit to construct or county land use permit and its'requirements (a CEQA analysis may be conducted.) NOTE: the stationary source must demonstrate that they initiated the land use permit process in a timely manner., The stationary source must retain documentation of closure and any associated justification of actions identified by the process hazardanalysis. CCHS interprets"actions"to include, but not be limited to, all recommendations made for changes to physical equipment and procedures, and for additional studies and information. The stationary source must also retain documentation of communisation to operating, maintenance and ether employees whose work assignments are in the process and who may be affected by the recommendations or actions.' D.1.6 Inherently Safer System Reports An Annual report on the Industrial Safety Ordinance is made to the Board of Supervisors in October each year. Each June,Contra Costa Health Services will request information from the stationary sources for this report. Part''of this information includes information on the inherently safer systems already implemented. The information on inherently safer systems should include a brief description of each inherently safer system that was implemented from June 1 — May 31 each year that meet the definitions of the inherent or passive levels for processes..where a Major Chemical Accident or Release could reasonably occur. The description should include the level of risk reduction(inherent or passive),and the basis for the inherently safer system implemented (e.g., FHA, Inherently Safer System Analysis, Review of Inherently Safer Systems for new processes or facilities).`' D.1.7 Definitions 1. "Active - Using controls, safety interlocks, and emergency shutdown systems to detect and correct process deviations, e.g., a pump that is shut off by a high level switch in the downstream tank when the tank is 90C10 full. These systems are commonly referred to as engineering controls."r1 2. Could Reasonably Occur 12= is a relative term that depends on the severity of the incident that qualifies a scenario as a Major Chemical Accident or Release.

Inherently Safer Systems Analysis — Performing a study to incorporate concepts of inherently safer systems. The analysis will include recommendations on incorporating inherently safer systems into a process. The analysis will include the documentation on how the study'was performed, the recommendations`from the study, and how'the recommendations were formulated. 6. Less Hazardous Form—Materials being handled under conditions that is considered leas hazardous. Less hazardous conditions can be accomplished by strategies that are either physical (lower temperatures, and/or pressures, dilution) or chemical (development of reaction chemistry that operates less severe conditions).Examples include; dilution, refrigerated liquids that are gases at standard temperatures and pressures, and operating at lower temperatures and pressures. 7. Major Chemical Accident or Release-is defined by the ordinance(§450-8.014(h))as " . . means an incident that meets the de,finition of a Level 3 or Level 2 Incident in the Community Warning System incident level classification system defined in the September 27,'1997 Contra Costa County guideline for the Community Warning System as determined by the'Department;or results in the release including, but not limited to, air, water, or soil'of a Regulated Substance and meets one or more of the following criteria: (1) results in one or more fatalities; (2) results in greater than 24 hours of hospital treatment of three or more persons; (3) causes on and/or off-;site property damage (including clean-up and restoration activities) initially estimated at $500,000 or more. On-site estimates shall be performed by the Stationary Source. Off-site estimates shall be performed by appropriate agencies and compiled by the Department.; (4) results in a flammable vapor cloud of more than 5000 pounds. 8. "Minimization Use smaller quantities of hazardous substances (also called Intensification),14 9. "Moderate— Use less hazardous conditions,a less hazardous form of a material, or facilities that minimize the impact of release of hazardous material or energy(also called Attenuation or Limitation of Effects)"zs 10. New Process - The addition'of a process that did not,previously exist or a major revamp of an existing process resulting'in a substantial change'in the process configuration orprocess chemistry. 11. "Passive-Minimizing the hazard by process and equipment design features which reduce either the frequency or consequence of the hazard without the active functioning of any device; e.g., the use of equipment rated for higher pressure."1 14 CC1'S,Inherently Safer Chemical Processes A Life Cycle Approach, 1996 s CCPS,Inhert-ndy Safer Chemical Processes A Life Cycle'Approach, 1996 D-16 Section D Date: September 12,2002 12. "Procedural Using operating procedures, administrative checks, emergency response, and other management approaches to prevent incidents,or to minimize the effects of an incident;»e.g.,hot-work procedures and permits. These approaches are commonly referred to as administrative controls."1 z 13. Process Any activity involving a regulated substance including any use, storage, manufacturing,handling,or on-site movement of such substances,or combination of these activities. For the purposes of this definition, any group of vessels that are interconnected, or separate vessels that are located such that a regulated substance could be involved in a potential release, shall be considered'a single process. (CCR Title 19 Section 2735.3(tt) 14. "Process.Flow Diagram—A diagram that shows the material flow from one piece of equipment to the other in a process. It usually provides information about the pressure,temperature,composition,andflow rate of the various streams,heat duties of exchangers, and other such information pertaining to understanding and conceptualizing the process.„1s 15. "Quantitative Risk Analysis—The systematic development of numerical estimates of the expected frequency andlor consequence of potential accidents associated with a facility or operation based on engineering evaluation and mathematical techniques."19 16. Safer Chemicals — Chemicals where the acute and chronic toxicity, flammability, reactivity,and instability are:lower. A chemical maybe safer in some of these hazard categories and higher in others. The facility needs to determine the impact from a release of a chemical based on the above hazards. The chemical with the least impact should be safer. 17. "Simplify— Design facilities that eliminate unnecessary 'complexity and make operating errors less'likely, and that are forgiving of errors that are made (also called.Error Tolerance)„20 18.

"Out-of-the-box" thinking is strongly encouraged. The content of this checklist'was extracted from COPS "Inherently Safer Chemical Processes:A Life Cycle Approach"', and"Process Minimization: Making,Plants Safer`2 The checklist questions are not always pertinent for an individual facility or for every phase of a project or an existing facility.' The checklist should be tailored for your facility and for the stage the checklist is being applied for new processes,as follows: • During the chemistry-forming (synthesis) phase' for product/process research and development to focus on the chemistry and process • During the 'facilities design scoping, and development prior to completion of the design basis to focus on equipment and configuration • During the basic design phase of the project' The'checklist should also be tailored for existing process in your facility to be used during a Process Hazard Analysis, when appropriate for the Process Hazard Analysis Team. Some items may need to be reviewed by a'team that is outside of the Process Hazard Analysis Team,because the personnel with the appropriate expertise or ability may not be a part of the'Process Hazard Analysis Team. Issues, such as considering the transportation of hazardous materials, may require the ability to renegotiate contracts with shippers. CCHS will review how the stationary source determined the appropriate checklist for that facility and for the stage of :.assessment, when the facility is audited or during an unannounced inspection. Approaches to inherently safer systems may be categorized into the following strategies: I. Minimize A. Inventory Reduction 1. Can hazardous raw materials inventory be reduced? a) Consider just-in-tune deliveries b) Supplier management including strategic alliance C) On-site generation of hazardous material from less hazardous raw materials 2. Can in-process storage and inventory be reduced? a)' Direct coupling of process'elements b) Eliminate or reduce size of in-process storage C)' Design''process equipment'involving hazardous material with the smallest feasible inventory 3.

Changes in reaction'phase'(e.g., liquid/liquid,'gas/liquid,or gas/gas) 3. Changes in the order in which raw materials are added D. Is it possible to dilute hazardous raw materials to reduce the hazard potential? By using: 1. Aqueous ammonia instead of anhydrous 2 Aqueous HCl instead of anhydrous 3 Sulfuric acid instead of oleum 4. Dilute nitric acid instead of concentrated fuming nitric acid 5. Wet benzoyl peroxide instead of dry E. Is It possible to design operating conditions such that materials that become unstable'at elevated temperatures or freeze at low temperatures heating and cooling medium will not be operating in those ranges? F. Can process conditions be changed to avoid handling;,flammable liquids above their flash points? G. ` Is equipment designed to totally contain the materials that might be present inside at ambient temperature or the maximum attainable process temperature(i.e., higher maximum allowable working temperature to accommodate loss of cooling, simplify'reliance of external systems such as refrigeration systems to control temperature such that vapor'pressure is less than equipment design',pressure)? H. For processes handling flammable materials,is it possible to design the layout to minimize the number and size of confined areas and to limit the potential for serious overpressure in the event of a loss of containment and subsequent ignition?

For flammable materials,can spills'be directed away from the storage vessel to reduce the risk of a boiling liquid expanding vapor explosion(BLEVE)in the event of a fire? M. Passive safety design is preferred. Can passive design be implemented? For example,to prevent or reduce fire damage, an active method is automatic water spray actuated by flame or heat detector; a procedural method by having an operator turn on the water spray, or passive method by using fire insulation. N. Can PSV's in flammable service be routed to flare header instead of atmosphere? IV. Simplify A. Can equipment be designed such that it is difficult or impossible to create a potential hazardous situation due to an operating'or maintenance error?Such as: May 17, 2002 Inherently Safer Systems Checklist Page 4 1 Easy operation of valves designed to prevent inadvertent errors 2.
