42 1.0 INTRODUCTION ERG Operating Company, LLC (ERG) is proposing to install a sales oil pipeline for the Foxen Petroleum Pipeline Project at the West Cat Canyon facility. This facility is located at 6085 Cat Canyon Road in Santa Maria, California and is identified by the Santa Barbara County Air Pollution Control District (SBCAPCD) as Stationary Source ID (SSID) # This Health Risk Assessment (HRA) is based on the Foxen Petroleum Pipeline reasonable worst case operational emissions. The purpose of this HRA is to estimate the public health impacts at the off-site Point of Maximum Impact (PMI), Maximally Exposed Individual Resident (MEIR), Maximally Exposed Individual Worker (MEIW), sensitive receptors, and any on-site receptors as a result of exposure to emissions from the project. As set forth in SBCAPCD guidance for the preparation of HRAs [1], risk values for the MEIR, MEIW, sensitive receptors, and any on-site receptors are compared to the following significant risk thresholds adopted by the SBCAPCD to assess whether public notification and risk reduction are required prior to project approval: Cancer risk of 10 per million Chronic hazard index of 1.0 Acute hazard index of 1.0 This study was conducted using the Hotspots Analysis and Reporting Program (HARP) Version 1.4f [2]. Section 2 of this HRA provides a description of the facility and the sources evaluated in this study. Section 3 summarizes the methodology used to conduct the analysis while Section 4 presents the results. Finally, the appendices provide supporting documentation. In any risk evaluation, a number of extremely conservative assumptions are made in order to provide an upper end but consistent estimate of human exposure and to calculate potential risks. Conservative assumptions are made in this risk assessment to provide an upper-bound estimate of the risk and to avoid underestimating the potential exposures and associated health risks. Thus, estimated cancer risks are upper-bound estimates and the actual incidence of cancer is almost certain to be lower. SCS Tracer Environmental 1-1 Introduction Air Quality Appendix Appendix 4 - Page 41 ERG Foxen Petroleum Pipeline

43 2.0 PROJECT DESCRIPTION 2.1 OVERVIEW ERG proposes to construct and operate a 2.9-mile dual pipeline system ( Foxen Petroleum Pipeline Project or Project ) along Foxen Canyon Road to transport crude oil from its Cantin tank battery located in the state-designated Cat Canyon oilfield between the communities of Sisquoc and Garey in northern Santa Barbara County. The proposed pipeline system would tie into the existing Phillips 66 Sisquoc Pipeline, a common carrier pipeline, for transport out of the County to a refinery destination and would replace the current practice of trucking ERG s crude oil production from the field. The proposed Project consists of construction and operation of two 8-inch diameter crude oil pipelines placed side-by-side in a single 15,080 linear foot-long trench, a new Lease Automatic Custody Transfer (LACT) unit, flow meters, a pig launch and retrieval system, and an electrically-driven pump system. Equipment for storage and pumping from the Cantin Lease tank battery would include: Two new 10,000-barrel heated shipping tanks, One new 3,000-barrel heated reject tank, One new 5,000-barrel oil storage tank, Two new 10,000-barrel emergency oil storage tanks, and One new 10 MMBTU/hr heater. The Phillips 66 tie-in would include the construction of small portions of aboveground equipment, including the pig receivers, piping and valves. Although each pipeline would have a throughput capacity of 25,000 barrels of oil per day (bopd) the lines would not be operated simultaneously. Oil production from the Los Alamos, Long Canyon, Williams Holding 303, Great Western Producers (GWP), and Cantin leases would contribute to the Project throughput. This oil would be transported from the leases via flow and gathering lines from the various production sites to the Cantin tank battery, where oil, water, and gas streams would be separated using existing separation facilities. Once separated, the oil would be transferred to the new storage tanks and pumped to the proposed pipeline for transport out of the County to refinery destinations. During maintenance periods, one pipeline would be shut down and the other would be in operation. However, there may be short periods of time when either both of the ERG pipelines and/or the Sisquoc Pipeline would need to be completely shut down for maintenance or emergency response. Therefore, ERG proposes to maintain the ability to temporarily use truck SCS Tracer Environmental 2-1 Project Description Air Quality Appendix Appendix 4 - Page 42 ERG Foxen Petroleum Pipeline

44 transportation if the dual pipeline system becomes inoperable for maintenance, repairs, or emergency operations. As of the date the Notice of Preparation (NOP) for the Environmental Impact Report (EIR) was issued (June 7, 2013), ERG s oil production from its Cat Canyon oilfield facilities was 474,500 barrels per year at an average 1,300 barrels per day. At approximately 160 barrels per truck, this represents an average of approximately 8 truck-loads per day and 2,900 truck-loads per year. Since issuance of the NOP, ERG s production has risen to approximately 3,400 barrels of oil per day, resulting in 21 oil truck trips per day to transport the oil from the fields. Without the operation of a pipeline, this trucking rate would continue to increase in response to rising field production. In addition to increased production from ERG s existing operations, ERG has applied for a permit to construct and operate another 233 oil and gas wells in the Cat Canyon Field. Other operators are expected to increase production from existing and new wells in the future. The proposed pipelines would negate the need for routine trucking of crude oil for ERG and potentially other operators. However, planned pipeline maintenance shutdowns or emergencies could require temporary trucking. Regularly scheduled maintenance shutdowns may occur every 1-2 years and during these planned shutdown periods, temporary trucking may resume for an estimated hours. Unforeseen emergency shutdowns may necessitate longer periods of temporary trucking activity. This trucking would occur between the GWP and Cantin tank batteries and the Phillips 66 pump station on Battles Road. Note that this HRA makes the conservative assumption that in the event of a pipeline shutdown, 25,000 bopd (the maximum operational capacity of the pipeline s permitted limit) would be transported by truck from ERG s Cantin and GWP tank batteries to the Battle s Pump Station. In reality, this maximum volume of daily production and pipeline throughput is only likely to be achieved if multiple operators, not just ERG, are contributing oil to the pipeline system. In the event that the pipeline system is temporarily shut down and trucking resumes, each individual company would be loading and trucking oil from their individual, respective facilities and loading racks. This would disperse the associated emissions over a wider region of the Cat Canyon oilfield and reduce the acute risks below the conservative assumptions of this report. 2.2 LOCATION The Foxen Petroleum Pipeline Project is located within ERG s West Cat Canyon facility. The pipeline itself extends north of the facility along Foxen Canyon Road to Santa Maria Mesa Road (see Figure 2-1). The West Cat Canyon facility is located at 6085 Cat Canyon Road in Santa Maria, California and is identified by the SBCAPCD as stationary source ID # The facility is primarily situated east of US Highway 101 along Cat Canyon Road. The facility is located in terrain with rolling hills and canyons. The area surrounding the facility is primarily rural (see Figure 2-2). The closest densely populated area is the community of Sisquoc to the north of the facility. Palmer Road, Dominion Road, Long Canyon Road, and Cat Canyon Road are public roadways that cross within the facility boundary.

All UTM coordinates listed are NAD83, Zone 10. See Figure 2-2 for the release locations grouped by HARP process description. In order to model the various sources, the following assumptions were applied: Cantin tank battery fugitive components were grouped and modeled as a volume source 20 feet by 20 feet with a release height of 2 feet. Pipeline fugitive components were divided into two groups representing the above ground sections at each end of the pipeline and each group was modeled as a volume source 3 feet by 3 feet with a release height of 1.5 feet. The pig receiver was modeled as a volume source 1 foot by 1 foot with a release height of 1.5 feet. Tanks were modeled as point sources in accordance with SBCAPCD guidelines. Crude oil loading racks were modeled as volume sources each 3 feet by 3 feet with a release height of 1.5 feet. LCO unloading emissions were modeled at the Cantin LCO tank release point. All sources operate 24 hours per day, 365 days per year, with the exception of pig receivers and the loading racks.

52 3.0 METHODOLOGY 3.1 OVERVIEW The Hotspots Analysis and Reporting Program (HARP) Version 1.4f [2] was used to estimate acute, chronic, and cancer public health impacts resulting from potential exposure to atmospheric emissions from the facility. Table 3-1 provides a summary of key terminology used in the analysis. TABLE 3-1 Key Health Risk Assessment Terminology Term Acute health impacts Chronic health impacts Cancer health impacts Multi-pathway substance Description Health effects that occur over a relatively short period of time (e.g. minutes or hours). The term is used to describe brief exposures and effects that appear promptly after exposure to pollutants emitted from a facility. Adverse non-cancer health effects that develop and persist (e.g. months or years) over time after long-term exposure to pollutants emitted from a facility. Theoretical probability of developing cancer assuming continuous lifetime exposure to pollutants emitted from a facility. A substance or chemical that once airborne from an emission source can, under environmental conditions, be taken into a human receptor (body) by inhalation and by other exposure routes such as after deposition on skin or after ingestion of soil contaminated by emissions from a facility. There are four steps involved in a health risk assessment: 1. hazard identification 2. exposure assessment 3. dose-response assessment 4. risk characterization For sources of air toxics, hazard identification involves identifying if a hazard exists, and if so, what are the exact pollutant(s) of concern and whether a pollutant is a potential human carcinogen or is associated with other types of adverse health effects. The California Office of Environmental Health Hazard Assessment (OEHHA) provides the latest information on whether substances are considered to cause acute, chronic, or cancer health impacts. Such information was incorporated into the HARP model using the latest health.mdb file provided by OEHHA. The purpose of the exposure assessment is to estimate the extent of public exposure to each substance for which potential cancer risk, acute non-cancer health effects, and chronic noncancer health effects will be evaluated. This involves emission quantification, modeling of environmental transport, evaluation of environmental fate, identification of exposure routes, SCS Tracer Environmental 3-1 Methodology Air Quality Appendix Appendix 4 - Page 51 ERG Foxen Petroleum Pipeline

53 identification of exposed populations, and estimation of short-term and long-term exposure levels. Peak hourly and average annual ground level concentrations are estimated at specific offsite locations using an atmospheric dispersion model, source-specific parameters (e.g. pollutant emission rates, stack dimensions, exhaust velocities, etc.) and representative meteorological data. Dose-response assessment characterizes the relationship between exposure to a substance and incidence of an adverse health effect in exposed populations. In quantitative carcinogenic risk assessment, the dose-response relationship is expressed in terms of a potency slope that is used to calculate the probability or risk of cancer to a substance. For non-cancer effects, the doseresponse data developed from animal or human studies are used to develop acute and chronic Reference Exposure Levels (RELs). The acute and chronic RELs are defined as the concentration at which no adverse non-cancer adverse health effects are anticipated. Risk characterization is the last step in the risk assessment analysis. In this step, modeled concentrations and public exposure information from the exposure assessment are combined with cancer potency slopes and non-cancer RELs to arrive at the estimates of public health impacts. Cancer risk at a specific location is the sum of the cancer risks from each substance emitted by the facility. Chronic health impacts at a specific location are determined by first calculating the hazard quotient (exposure level divided by REL) for each substance emitted by the facility. Since substances affect different parts of the human body, the pollutant specific hazard quotients are summed according to target organ. The chronic hazard index is the highest target organ total value. Acute health impacts are calculated using the same approach as used for chronic health impacts. The SBCAPCD has developed significance thresholds for the risk assessment process. For example, the SBCAPCD has established significance thresholds of 10 in one million for cancer risk and a Hazard Index of 1.0 for non-cancer risk. Cancer risk is defined as the upper-boundary incremental probability of an individual developing cancer over a lifetime as a result of exposure to certain identified potential carcinogens. The cancer risk significance threshold is locationspecific and is intended to ensure a sufficient safety margin to prevent a single project or activity from causing a substantial contribution to the overall cancer risk for a given area. If any of the above significant risk thresholds are met or exceeded, the SBCAPCD may require public notification and possibly risk reduction. 3.2 MODEL SELECTION The Hotspots Analysis and Reporting Program (HARP) Version 1.4f [2] was selected to conduct the analyses in this study. HARP integrates the U.S. Environmental Protection Agency (EPA) Industrial Source Complex Short Term (ISCST3) model and the Building Profile Input Program (BPIP) into one seamless software application. The rationale for selecting this model is as follows: SCS Tracer Environmental 3-2 Methodology Air Quality Appendix Appendix 4 - Page 52 ERG Foxen Petroleum Pipeline

54 HARP is the software required by the SBCAPCD for conducting HRAs HARP is in the public domain and readily accessible ISCST3 can model multiple sources ISCST3 can model the effects of aerodynamic downwash on point source emissions due to nearby buildings ISCST3 can predict concentrations at gridded and discrete receptor locations ISCST3 can use actual meteorological data to simulate the atmospheric conditions that affect the transport and dispersion of air pollution from on-site sources the COMPLEX1 screening model dispersion algorithms are incorporated into ISCST3 for receptors in complex terrain 3.3 MODEL OPTIONS Table 3-2 summarizes the modeling software and options used in this study while Table 3-3 summarizes the exposure pathways included in the analysis. Figure 3-1 displays the dispersion modeling domain while Figure 3-2 displays a map of the nearby schools, residential areas, and worker areas that were modeled as sensitive receptors (see Table 3-4 for details).

Runs 1 through 4 were used to locate the maximum pasture receptor for the 1988 and 1989 meteorological data. Runs 5 through 8 were used to identify areas with the highest impacts and to determine the PMI, MEIR, and MEIW using fine grids for the 1988 and 1989 meteorological data. Runs 9 and 10 were used to generate PMI, MEIR, and MEIW receptor reports and cancer burden reports without causing overflow errors in HARP.

69 4.0 RESULTS This section presents the estimated public health risks for the Project using both the 1988 and 1989 meteorological data. For each meteorological year, results are presented for the: Point of Maximum Impact (PMI) Maximally Exposed Individual Resident (MEIR) Maximally Exposed Individual Worker (MEIW) Sensitive receptors within two kilometers In accordance with SBCAPCD HRA guidelines [1] : The PMI may be a boundary receptor, grid receptor, or a sensitive receptor. No residence or business is required to occupy the PMI. The 70 year (adult resident) exposure duration with the Derived (Adjusted) Method were used to determine the PMI and MEIR results for cancer risk. The 40 year worker exposure point estimate was used to determine the MEIW results for cancer risk. The Derived (OEHHA) Method was used to determine the PMI and MEIR results for chronic non-cancer risk. The worker exposure point estimate was used to determine the MEIW results for chronic non-cancer risk. All applicable pathways (i.e. inhalation, dermal, soil, mother s milk, home grown produce, chicken, eggs, beef, dairy, and pigs) were included in all analyses. The HARP simple (concurrent max) method was used to determine the PMI, MEIR, and MEIW results for acute non-cancer risk. Table 4-1 displays the PMI, MEIR, and MEIW results for the 1988 meteorological data. Table 4-2 displays the PMI, MEIR, and MEIW results for the 1989 meteorological data. The residential chronic and 70 year adult residential cancer impacts include all pathways of exposure to be conservative. The 40 year worker cancer impact includes just the inhalation, dermal, and soil pathways since the HARP model automatically excludes other non-applicable pathways (e.g. home grown produce). Table 4-3 displays the results for sensitive receptors (i.e. schools, residential areas, and worker areas within two kilometers) based upon the 1988 meteorological data while Table 4-4 displays the sensitive receptor results for the 1989 meteorological data. Both tables include all pathways of exposure. SCS Tracer Environmental 4-1 Results Air Quality Appendix Appendix 4 - Page 68 ERG Foxen Petroleum Pipeline

70 Table 4-5 summarizes the cancer burden for census blocks within 15,000 meters of the facility s center (UTM Zone 10, mE, mN). Cancer burden was calculated by first multiplying the estimated 70 year adult residential cancer risk (including all pathways) at each census block by the census block s associated population and then summing the results over all of the census blocks evaluated. Census data from 2000 was used in the analysis since the 2010 census data has not yet been released for the HARP model. Based upon the analysis, the MEIR, MEIW, and sensitive receptor results for the Project are all below the SBCAPCD significant risk thresholds for both meteorological years. As such, the analysis indicates that the Project will not have a significant impact for health risk based on the thresholds established by the SBCAPCD. See Figures 4-1 and 4-2 for the Project impacts. See Appendix C for the HARP input and output files used to conduct the analysis including detailed reports by pollutant and by source for the PMI, MEIR, and MEIW receptors.
