´╗┐California Environmental Protection Agency Air Resources Board Public Workshop to Discuss Proposed Amendments to the AB 2588 Guidelines Regulation July 27, 2006

Slide 2

Presentation Overview "Problem areas" Program Proposed Amendments Implementation of Proposed Amendments Response to Comments from Previous Workshops Preliminary Cost Estimates Next Steps

Slide 3

"Problem areas" Program

Slide 4

AB 2588 "Problem areas" Program State Law sanctioned in 1987 Evaluates wellbeing dangers from offices that transmit air toxics, including diesel PM Public advised of huge wellbeing dangers Requires noteworthy dangers to be diminished

Slide 5

Key Provisions and Implementation Key Provisions Emission reporting, Health hazard appraisal, Public notice, and Risk decrease Implementation ARB sets reporting necessities by revising Guidelines direction OEHHA creates hazard appraisal rules Local regions actualize program, and set warning and hazard lessening limits

Slide 6

AB 2588 "Problem areas" Achievements Basis for first statewide air toxics stock Voluntary diminishment of a large number of pounds of toxics from modern sources Provides information for recognizable proof of dangerous air contaminants and other control measures Provides data to general society about air contamination from stationary sources

Slide 7

Proposed Amendments

Slide 8

Proposal Does Not Change "Problem areas" Process Proposed corrections don\'t adjust the center of the "Problem areas" Program Proposal redesigns logical data on harmful substances and danger appraisal strategy Proposal influences hazard counts and pertinence, not prepare

Slide 9

What Changes Are Being Proposed for the Guidelines Regulation? Adjust reporting prerequisites to ATCM Update diesel motor prerequisites to reflect diesel particulate malignancy intensity Incorporate latest OEHHA hazard appraisal rules, including new wellbeing values Update substance list Only little rate of influenced offices should go past ATCM prerequisites

Slide 10

Recap of Diesel Proposal Modify reporting edge for diesel motors Define "diesel motor just office" Align stock answering to evade duplication Allow adaptability in selecting reporting year Provide screening hazard appraisal apparatuses Address open notice process Limit State charges

Slide 11

Revisions Since Last Workshop New diesel motor \'Area XI\' revamped and rearranged Modified diesel motor reporting necessities to adjust to ATCM Add clearing up dialect to permit areas to ask for extra data if important to finish evaluation

Slide 12

OEHHA Health Risk Assessment Guidelines Adopted by OEHHA in 2003 Replaces 1993 CAPCOA HRA Guidelines in "Problem areas" direction Includes OEHHA-endorsed disease strength for diesel PM, and wellbeing values for different substances Already being used by regions as a feature of all danger assessments

Slide 13

Updating the List of Substances (Appendix A) Twelve new substances now secured by "Problem areas" reporting Individual substances included under existing classes of recorded substances Individual congeners of Dioxin-like PCBs, and PAHs Expand existing class of Brominated diphenyl ethers and Trimethylbenzenes \'Level of precision\' reflects new wellbeing values Corrections to CAS number or substance name

Slide 14

Substances With Potential to Affect Facilities in California Naphthalene has another growth power Combustion side effect - emanation variables are accessible Crystalline silica has another perpetual wellbeing esteem Emitted from total offices and other dust sources Test technique being worked on Acrolein has an overhauled intense wellbeing esteem Combustion result discharged at low levels No demonstrated source test strategy accessible

Slide 15

Implementation of Proposed Amendments

Slide 16

Aligning "Problem areas" with Stationary Diesel Engine ATCM 2005 ATCM reporting prerequisites fulfill "Problem areas" outflow reporting necessities Updated discharge data (2007) reflecting new controls might be utilized Compliance with ATCM will meet "Problem areas" necessities for most offices Facilities with numerous diesel motors close living arrangements may trigger open warning and extra hazard decrease

Slide 17

Facilities Potentially Subject To Additional "Problem areas" Requirements A little rate of influenced offices might be liable to extra Hot Spots prerequisites which are far beyond ATCM necessities Facilities with various motors Multiple prime motors Prime and reinforcement motors Multiple reinforcement motors Facilities with different wellsprings of harmful discharges which could conceivably have beforehand been liable to "Problem areas"

Slide 18

Facilities With Multiple Engines (no different toxics) "Problem areas" survey important to decide leftover danger after ATCM execution ATCM sets working/emanation limits on a for every motor premise "Problem areas" materialness in light of all motors working at an office Some offices have many reinforcement motors, and the danger must be assessed

Slide 19

Facilities With Other Sources of Toxic Emissions Facilities may surpass region\'s danger edges when diesel danger is added to hazard evaluation Facilities beforehand subject to "Problem areas" should reflect new data in quadrennial upgrade Districts will inform new offices that get to be liable to "Problem areas" Screening tables and HARP accessible to address diesel hazard

Slide 20

Options for Facilities with Multiple Diesel Engines Reporting edge (20 motor hrs/yr) for diesel motors is just the initial step for Screening wellbeing hazard evaluations tables accessible for follow up screening process Risk evaluation programming (HARP) accessible on ARB\'s website page to accomplish more refined examination Facilities with critical lingering danger may need to diminish emanations more distant than what is required by the ATCM

Slide 21

Public Notification District decides hazard edge for open notice (typically 10/million) District decides prerequisites for leading open notice Notification by means of web or neighborhood daily papers Notification letters to adjacent occupants Public discussion meeting

Slide 22

"Problem areas" Program and Proposed ATCM for Agricultural Engines Agricultural motor ATCM being worked on Align proposed ATCM and "Problem areas" program necessities Streamline consistence process Avoid duplicative prerequisites

Slide 23

Response to Comments on Proposed Amendments from Previous Workshops

Slide 24

ARB Staff Responses to Questions from Workshops Are diesel motor crisis operations subject to "Problem areas" reporting? No, under the ebb and flow proposition crisis operations are not subject to AB 2588 reporting Definition of "Crisis Operations" will be the same as definition in ATCM Includes the loss of electrical force past the sensible control of the office Includes the pumping of water or sewage to keep a surge or sewage flood

Slide 25

ARB Staff Responses to Questions from Workshops (cont.) Are versatile motors subject to "Problem areas"? Yes, yet just if operations are normal and unsurprising May affect offices that have various diesel motors or numerous wellsprings of toxics Facility administrator would be in charge of reporting movement information, including exercises of outsider contractual workers

Slide 26

ARB Staff Responses to Questions from Workshops (cont.) Are motors under 50 hp subject to "Problem areas"? Under the present proposition, locale have adaptability to demand data on under 50 hp motors if a region decides it is important to evaluate office sways Operation must be normal and unsurprising Mainly an issue for offices that have numerous diesel motors or different wellsprings of toxics

Slide 27

ARB Staff Responses to Questions from Workshops (cont.) If a motor is excluded from the stationary motor ATCM, will it be absolved from "Problem areas"? Not consequently Source would be liable to standard survey handle Most ATCM-exempted exercises are expected to be generally safe and screen out ahead of schedule simultaneously

Slide 28

ARB Staff Responses to Questions from Workshops (cont.) Are vehicular sources subject to AB 2588? No, discharges from vehicular sources (autos, trucks, and so on.) are not subject to AB 2588 Fugitive dust from vehicle movement may should be accounted for if office is as of now in AB 2588

Slide 29

Preliminary Cost Estimates

Slide 30

Proposed Amendments Do Not Change "Problem areas" Program Costs Amendments call for audit of new substances taking into account new investigative data, however don\'t expand any current "Problem areas" expenses Many offices with diesel motors as of now in "Problem areas" may not see any adjustment in charges or costs New offices with just diesel motors will pay an ostensible State charges (~$35) Some huge mechanical offices may have costs identified with substances with new wellbeing values

Slide 31

Approach for Estimating Facility Costs Facility consistence costs activated by new corrections incorporate incremental expenses far beyond ATCM and past "Problem areas" prerequisites Diesel PM stock (secured by ATCM as a rule) Health hazard evaluation ($3,000 - $20,000) Inventory overhaul ($200 - $2,000) Public notice ($0 - $30,000) Residual Risk decrease ($500 - $40,000 per motor) State charges ($35-$6,363) and District charges ($35-$14,000) Additional costs likewise connected with reporting and appraisal of new substances

Slide 32

Costs for Facility with Multiple Backup Engines Assumptions: Facility never subject to AB 2588 2 reinforcement diesel motors working 40 hrs/yr ATCM stock submittal fulfills AB 2588 reporting necessities Screening HRA shows danger is <10/million Costs: State expense ($35/yr) + District charge ($150/yr) Total costs under $200/year
