SUMMARY Geotechnical Exploration Inc. (GEI) performed a Phase I Environmental Site Assessment (ESA) of the subject property between 7 March and 31 March 2005. The property is located in the east quadrant of the City of Carlsbad, which is in northwest San Diego County. The property is irregularly shaped and occupies an area of 43.19 acres. Historically, this part of the city was used for agriculture, with various property owners growing dry, row-crop produce or ornamental plants. The subject property was undeveloped until the early 1980s when it was cleared for agricultural use. The parcel has remained in intermittent agricultural use until present. Currently the site exists as fallow agricultural land. The following sections summarize GEI's independent conclusions based on our best professional judgment and the information and data available to us at the time of the assessment. Factual information regarding operations, conditions, and test data provided by the client, owner, or their representative has been assumed to be correct and complete. 1.1 Conclusions The subject property was undeveloped and unused between 1955 and the early 1980s. It was cleared of native vegetation in the early 1980s and has been in agricultural use intermittently since that time. There are no overt indicators of agricultural chemical usage on-site such as patchy vegetation that might suggest Rancho Milagro Development Job No. 04-8849 Carlsbad, California Page 2 the presence of herbicides in the soil or areas of unusually dense growth that might suggest high levels of fertilizers in the soil. Two soil samples were collected for chemical analysis to determine if pesticide or herbicide residues are present in the soil. The results of these analyses will be provided in a letter report, once the analyses are completed. There are no structures onsite and therefore testing for asbestos containing material, lead-based paint, or radon gas was not required. The site is largely cleared of vegetation with patches of non-native vegetation remaining. The Agua Hedionda Creek streambed runs through the southwest side of the property. This riparian habitat is considered a sensitive biological resource by state and federal resource agencies and is subject for Sunny Creek. No indicators of hazardous materials usage or disposal were observed and the site is free ofany significant accumulation of solid waste. GEI's review of the adjacent properties did not reveal any significant environmental issues that could affect the value of the property or constrain development. 1.2 Recommendations No environmental concerns that would require further investigation were discovered during the course of this ESA. It is suggested that the property owner periodically contact the San Diego County Department of Environmental Health to check the regulatory status on the farmland adjacent to the subject property. 1.3 Proiect Staff The following individuals conducted the field work and prepared the report for this Phase I Environmental Site Assessment.

METHODOLOGY AND REPORT LIMITATIONS The purpose of an ESA is to evaluate the environmental status of the subject property and surrounding area with the intent of identifying any existing or potential features that could constrain development of the property or represent a significant environmental liability. An ESA is primarily a screening tool designed to identify environmental "red flags." GEI often collects soil screening samples from properties that have been in agricultural use to provide an indication of the presence of agricultural chemical residues. Two such samples were collected and the analytical results are pending. If potential issues or constraints are identified, a Phase II Environmental Site Investigation (ESI) involving more extensive sample collection and analysis may be required to quantify the significance of impact to the property. This report is intended solely for the use of the Client in connection with any near term real estate transaction involving this property. This report is not to be quoted, in whole or in part, or otherwise relied upon for any other purpose. This report may be released at the Client's discretion for 6 months following issuance. After 6 months, GEI should be contacted to determine if conditions on the ground have changed sufficiently to require revision of the report. It should be emphasized that this ESA focuses on past and present practices that could represent a potential liability to the owner or buyer of the property under current environmental laws and regulations. The findings of this assessment are apparent from the data gathered and the degree of access to the property Rancho Milagro Development Job No. 04-8849 Carlsbad, California Page 4 permitted for the PS site visit. Environmental sampling and chemical analysis was not conducted as part of this assessment. 2.1 Assessment Activities All GEI ESAs are fully compliant with the requirements of ASTM Standard E 1527-00 and current professional standards. As per these requirements, PS performed a visual inspection of the property and the surrounding area, an analysis of aerial photographs and maps, and a review of files maintained by the City ofCarlsbad and the County of San Diego, as well as interviews with key individuals. In addition, county, state and federal databases were searched for records of hazardous materials violations on the subject property and all locations within one mile of the property. The Phase I Assessment for the subject site included the following tasks: 1. Survey of the property to observe current use of the site and adjacent properties, for indications of potential contamination and/or the presence of hazardous materials. 2. Interview knowledgeable sources regarding current and previous uses of the subject property and adjacent properties. 3. Review of state/federal lists to assess the potential for hazardous materials generators or leaking underground storage tanks within the vicinity of the subject property. 4. Review of existing documentation, as available, regarding prior investigations, events, or conditions on the site and in the immediate vicinity <IHI Rancho Milagro Development Job No. 04-8849 Carlsbad, California Page 5 relating to spills, discharges, or other activities that could represent environmental concerns or indicate the presence of hazardous material. 5. Search Sanborn Insurance Maps for the subject site and immediate surrounding area. 6. Review historical aerial photographs of the subject site and immediate surrounding area. 7. Review topographic maps of the subject site and immediate surrounding area. 8. Preparation of a report documenting findings, recommendations and professional opinions regarding observed or suspected environmental m constraints. 2.2 Regulatory Agency Data Review The regulatory agency report provided is based on an evaluation of the data collected and compiled by a contracted data research company. The report is based on a radius search that focuses on both the subject and neighboring sites that may impact the subject property. Neighboring sites listed in governmental environmental records are identified within a specific search distance. The search distance varies depending upon the particular government record being checked. The search is designed to meet the requirements of the current industry approach and the ASTM Standard E 1527-00. The information provided is assumed to be correct and complete. Rancho Milagro Development Job No. 04-8849 Carlsbad, California Page 6 2.3 Report Limitations This report is prepared solely for the use of the Client in accordance with ASTM standards. Our professional services have been performed, our findings obtained and our recommendations prepared in accordance with customary principles and practices in the field of environmental science. This company is not responsible for the independent conclusions, opinions or recommendations made by others based on the field exploration presented in this report. It should be noted that all surficial environmental assessments are inherently limited in the sense that conclusions are drawn and recommendations developed from information obtained from limited research and site evaluation. A comprehensive subsurface survey was not performed as part of this study. Subsurface conditions may differ from the conditions implied by the surface observations. Additionally, the passage of time may result in a change in the environmental characteristics at this site and surrounding properties. It must be noted that no investigation can absolutely rule out the existence of any hazardous materials at a given site. This assessment has been based upon prior site history and observable conditions and activities. Existing hazardous materials and contaminants can escape detection using these methods. The work performed in conjunction with this assessment and the data developed are intended as a description of available information at the dates and location given. This report does not warrant against future operations or conditions, nor does it warrant against operations or conditions present of a type or at a location not investigated. In addition, this report is not intended as a regulatory agency compliance/safety audit or for the purpose of ensuring that all applicable permits and/or operating procedures are current and/or appropriate.

PROPERTY DESCRIPTION AND HISTORY The subject property consists of 43.19 acres of agricultural land located on the east side of Sunny Creek Road, south of College Boulevard, in the City of Carlsbad's east quadrant. This coastal community is located in northwest San Diego County. 3.1 Property Information Address No street address - East of Sunny Creek Road, Carlsbad, CA 92009 Assessor's Parcel Number 209-060-61 - County of San Diego Property Owner Xavier Sustaeta Land Use Agriculture Subject Age Undeveloped as far back as 1955 Site Configuration Irregularly shaped, sloping down from east to west Number of Buildings No structures Other Improvements None Parking None Site Drainage Unimproved, natural drainage downslope to the west Utilities: Electric None Water Carlsbad Municipal Water District Sewer None 3.2 Topography The location and natural topography of the site and vicinity are shown on the excerpt of the San Luis Rey USGS 7.5 minute topographic map provided in Appendix A (reference #1). The immediate area can be characterized as west- southwest sloping terrain and drainage ways that trend into the westward flowing Agua Hedionda Creek watershed, which is also located within the southern portion of the subject property. The USGS map shows the natural (pre-graded) elevation of the site to range between 100 feet (MSL) along this watershed to approximately 200 feet at the northeastern portion ofthe property. Rancho Milagro Development Carlsbad, California Job No. 04-8849 Page 8 There are no drainage improvements on the site. Surface runoff drains southwest across the into Agua Hedionda Creek. 3.3 Geology and Soils U.S. Department of Agriculture data, shows the property is overlain by the Diablo Las Flores Association which consists of well drained clays and moderately well drained loamy fine sands that have a subsoil of sandy clay on slopes of 9-30% (reference #2). The specific soil types within this association that are found on the subject property are described on the table below.

Rancho Milagro Development Job No. 04-8849 Carlsbad, California Page 9 3.4 Hvdrology The California Regional Water Quality Control Board (RWQCB) assigns beneficial uses to all water bodies in the state as means of preserving and/or improving the water quality of the receiving waters of the state. The subject property is located in the Los Monos Hydrologic Subarea, which is a part of the larger Agua Hedionda Hydrologic Area with the Carlsbad Hydrologic Unit. The RWQCB has designated the following beneficial uses for groundwater in the Los Monos Subarea: agricultural water supply, municipal water supply industrial water supply, process water and freshwater habitat (reference #3). The western edge of the property lies within the lOO-year floodway and floodplain. The portion of the property east of the lOO-year floodplain lies within the 500-year floodplain. A floodplain map is provided in Appendix A to define the limits of these areas (reference #4). There is no record of permitted wells on the site according to State of California regional ground water maps, thus depth to groundwater at the site is unknown. Groundwater movement is to the southwest following surface drainage patterns. The overall groundwater gradient is west toward the Pacific Ocean (reference #5). 3.5 Current Use The property is currently in agricultural use, although at the time of this survey the land was being fallowed. The property is totally cleared of vegetation, except along Agua Hedionda Creek, which supports willow riparian vegetation. Given the absence of activity, it is considered unlikely that any conditions attributable to the present use of the property pose a significant environmental impact or constraint to development ofthe property. Rancho Milagro Development Carlsbad, California Job No. 04-8849 Page 10 3.5.1 Adjacent Properties Land use on the adjacent properties is described in the table below. Direction Land use North Farm land Northeast Farm land Northwest Farm land and equine stable South Farmland and low density residential Southeast Undeveloped land. Southwest Undeveloped land East Farm land West Residential development - moderate density The property is in an area that 50 years ago was either undeveloped or in agriculture. Much of the area to the east is still in active agricultural or equine use. A planned residential community was constructed to the west of the site within the last five years. The future extension of College Boulevard will cross above the north end ofthe parcel. It is our opinion that the adjacent properties do not represent an environmental constraint to the subject property. The adjacent farmland could potentially be a source of agricultural chemical residues. The property owner is advised to monitor the status of agricultural chemical use on adjacent properties through periodic contact with the San Diego Department of Health Services. 3.6 Prior Use of Property Research into the site history and past use of a property represents a crucial component of any due diligence environmental assessment. Historical uses which may have caused environmental impacts on the property are often neglected, and Rancho Milagro Development Carlsbad, California Job No. 04-8849 Page 11 may be associated with previous occupation by service stations, automotive businesses, dry cleaners, metal plating operations, manufacturers, farms or landfills. The subject property was undeveloped and existed as natural habitat until the mid- 1980s, when it was cleared and plowed for agricultural use. No other uses of the property were identified during the course of this review. It has never been used for industrial, residential or community use in the past 50 years. Given the agricultural use of the property it was considered prudent to collect soil samples for analysis for agricultural chemicals. The results of these analyses will be provided in a separate letter report once they become available. 3.6.1 Historical Aerial Photograph Review A review of the San Luis Rey USGS map of 1968, Rev. 1975 was performed along with an examination of historical aerial photographs dating back to 1960, using the archives of the County of San Diego Cartographic Services Department (reference #5), Aerial Fotobank, Inc.(reference #6), Terra Server Image Viewer (reference #7) and GlobeXplorer Aerial Imagery (reference #8). The photos reviewed included the years 1960, 1967, 1974, 1989, 1995, 2002 and 2004. Source Date Flight/Frame No. San Diego County Aerial Fotobank Terra Server USA GlobeXplorer 1960 1967 1974 1989 1995 2002 2004 SDCT2/T11, 5-74 GS-VBTA, 172 SDPD, 33-17 WAC(West) #1-215 #1107 USGS (-117.276 x 33.145) 92008 Rancho Milagro Development Job No. 04-8849 Carlsbad, California Page 12 A review of the earliest photos (1960 and 1967) showed the subject site's natural, undisturbed topography, with essentially no disturbance to the native groundcover. No structures or other evidence of human construction was observed on the site. Although large areas of natural, undisturbed groundcover were also shown outside and near the perimeter of the site, adjacent properties to the east and west (north of Agua Hedionda Creek) were shown cleared of their natural ground cover and graded for agricultural operations. The nearest structures in 1960 and 1967 appeared to be an agricultural related complex located immediately west of the site, across an unpaved utility road that generally borders the property boundary. Additional small structures were also shown located along the north side of Agua Hedionda Creek, immediately adjacent to the subject site's eastern perimeter. The nearest significant non-agricultural activity was the McClellan Palomar Airport, located approximately a mile and a half south ofthe site. The first sign of significant residential and commercial development near the site was evident on the 1974 photo, which showed the residential community bordered by Calaveras Drive and El Camino Real approximately V2-mile west of the site, along Agua Hedionda Creek. Also, nearby commercial development was shown initiated east of El Camino Real by the grading and construction of Faraday Avenue and associated business structures located approximately y2-mile south of the site. These developments are also shown on the 1968 USGS map (revised 1975). Throughout this period, the subject site remained undisturbed. The 1989 photo showed an increase in the density of commercial development south of the site, along El Camino Real, as well as residential community development approximately y2-mile northeast of the site. An increase in agricultural operations was also evident in the immediate vicinity, including the center portion the site, which was shown cleared and graded for agriculture. 9 Rancho Milagro Development Job No. 04-8849 Carlsbad, California Page 13 The 1995 photo showed the site and adjacent properties to be essentially in their most recent configuration of growing fields and associated operations structures and utility roads. An initial alignment of Sunny Creek Road was also shown along the south side of Agua Hedionda Creek, just outside the subject site's southwest border. The land between Sunny Creek Road and El Camino Real, however, remained undeveloped. The 2002 photo showed the initial grading and construction of the residential community located on this land area, including the current alignments of Sunny Creek Road, College Boulevard, and the complex of residential streets serving this development. The 2004 photo showed the site and adjacent properties to be in today's configuration. Based on the photo/map review, the current use and configuration of the site and vicinity was developed into agricultural uses prior to 1960, with subsequent residential and commercial uses developed from the 1970s into the present day. Residential development nearest the site is less than 5 years old and has only slightly modified the original topographic condition of the area. There were no observable current or prior uses that would warrant a significant environmental concern. Nevertheless, contamination or any impacts on the site or from adjacent and nearby land uses cannot be precluded by the historical review alone. No further historical investigation is recommended at this time. 3.6.2 Sanborn Maps No historical Sanborn maps are available for the subject area. The lack of Sanborn mapping suggests that the area was not significantly developed with industrial or commercial land uses in the past. Rancho Milagro Development Job No. 04-8849 Carlsbad, California Page 14 IV. ENVIRONMENTAL HAZARDS ASSESSMENT A variety of environmental issues and hazards can constrain development at a given site. These potential issues include chemical hazards such as the presence of asbestos, agricultural chemical residues or PCBs and biological constraints such as the presence of wetlands and endangered species. 4.1 Description of Asbestos Hazards Asbestos can be found in almost any building material and is routinely found in insulation, blown acoustic ceiling finishes, flooring and roofing materials. Less commonly used as a building material since the mid-1970s, asbestos is still in use or distribution in certain materials such as flooring and roofing. Friable asbestos is considered more hazardous than non-friable asbestos because it can become more easily airborne and thus is more likely to enter the respiratory system, where it can lead to serious health problems. Inhalation of airborne fibers is believed potentially to lead to lung diseases and cancer. 4.1.1 Asbestos at the Subject Site There are no structures on the property and thus no testing for asbestos containing materials (ACM) was conducted. There are no asbestos related concerns associated with use of this property. 4.2 Description of PCB Hazards Polychlorinated biphenyls (PCBs) have been used in hydraulic fluids and dielectric (insulating) fluids in transformers, capacitors, and fluorescent light ballasts. PCB- containing fluids were used mainly in indoor locations to minimize the possibility of fire if electrical equipment overheated. PCBs were also used in transformers Rancho Milagro Development Job No. 04-8849 Carisbad, California Page 15 mounted on overhead power supply lines. The primary hazard associated with PCBs are fire-related damage to PCB-filled equipment. The PCBs vaporize and may be converted to dioxins and furans that are toxic through ingestion and inhalation. A secondary potential hazard is posed by spills and leaks that can contaminate soil and groundwater. PCBs are toxic through ingestion, but do not represent a significant inhalation hazard due to their low volatility. 4.2.1 PCBs at the Subject Property No PCB-containing equipment was observed on the subject site. No overhead power lines with potentially PCB containing transformers were observed anywhere on or adjacent to the property. No ground mounted transformers were observed on or adjacent to the property. 4.3 Description of Leaking Underground/Above-ground Storage Tank Hazards Underground and above-ground storage tanks (USTs & ASTs) are found on many residential and commercial properties. They are used for storing fuel, waste oils, solvents, and other waste and hazardous materials. The principal hazard from USTs and ASTs is leakage of contents due to corrosion of the tanks or lines. The leakage may result in migration onto the subject property and/or other properties of the stored material via the media of soil or groundwater. Soil and groundwater contaminated by the contents of USTs/AGTs can constitute health hazards. Clean- up of contaminated soil and/or groundwater and subsequent litigation is often costly. Rancho Milagro Development Job No. 04-8849 Carisbad, California Page 16 4.3.1 USTs/AGTs at the Subject Property No USTs or AGTs were observed on the subject property during the site survey. No USTs or AGTs were identified during the review of government records, historical site searches, or during interviews with the property owner, his agent and neighbor. 4.4 Description of Hazardous Materials Activity Migration of chemical contaminants is the primary risk associated with the use or disposal of hazardous materials. Skin rashes, central nervous system disorders and possibly cancer could potentially result from inhalation of gases and vapors or drinking contaminated water. Clean-up of contaminated conditions and subsequent litigation can be very costly. In the course of the environmental assessment, government records are checked for evidence of waste disposal at or near the site and an on-site survey is performed to detect any overt sign of hazardous materials use or disposal. In addition, historical Sanborn Insurance maps and/or aerial photographs of the site are reviewed for evidence of industrial operations or waste disposal activities. 4.4.1 Hazardous Materials/Waste Activity at the Site No evidence of hazardous materials usage was observed during the site survey or uncovered in the review of government records and historical aerial photographs. It is considered highly unlikely that there are any hazardous materials related impacts present on the subject property. <IHI Rancho Milagro Development Job No. 04-8849 Carisbad, California Page 17 4.5 Additional Hazards The presence of significant quantities of paints, fertilizers, soil amendments, and maintenance chemicals are examples of every day materials that can pose a hazard/risk to the environment and constrain development of the property. The following paragraphs discuss these miscellaneous hazard types as they relate to the subject property. 4.5.1 Property Housekeeping The property is undeveloped, largely vegetated with non-native species and free of solid waste. There are no general concerns relating to the physical condition of the property. No further action or investigation is needed. 4.5.2 Drinking Water Drinking water can be contaminated with lead, petroleum products, solvents, and any other chemical substances that migrate into the soil or groundwater table. Municipal water departments are required to treat and analyze potable water supplies prior to public use to assure the water meets current government standards for drinking water quality. The property is not currently hooked up to the local municipal water supply. When the property is developed, water will be provided by the CMWD. Staff at the CMWD indicated that their water supply is purchased from the San Diego County Water Authority which, in turn, purchases water from the Los Angeles Metropolitan Water District which supplies a blend of California Water Project and Colorado River water. According to CMWD the water supplied to the subject property meets or exceeds all USEPA drinking water standards, including the standard for lead content (reference #9). <IHI Rancho Milagro Development Job No. 04-8849 Carlsbad, California Page 18 No further action or investigation ofthe domestic water supply is necessary. 4.5.3 Urea Formaldehyde Foam Insulation Urea formaldehyde foam insulation (UFFI) was used during the 1970s and eariy 1980s to re-insulate buildings with little or no existing insulation. Urea and formaldehyde were mixed with a foaming agent and then injected into the walls of buildings, A problem can ensue if excess formaldehyde is present in the mixture. Toxic formaldehyde gas can slowly escape from the foam and permeate the building, UFFI can off-gas for up to a year after installation and can cause eye, nose, and throat irritation, disturbed sleep, and allergic reactions. There are no structures onsite and thus no UFFI present. 4.5.4 Review of Other Hazards and Constraints During the course of the site survey, no evidence of waste pits, ponds, clarifiers, drywells, landfills, or illegal dumping activity was observed on or adjacent to the subject property. 4.5.5 Wetlands Agua Hedionda Creek crosses the western portion of the property. This creek constitutes sycamore oak riparian woodland, a habitat type considered sensitive by state and federal resource protection agencies. In addition, patches of coastal sage scrub habitat were observed on north facing slopes above the riparian habitat. Coastal sage scrub is another type of sensitive habitat protected by state and federal regulation. Rancho Milagro Development Job No. 04-8849 Carisbad, California Page 19 4.6 Earthquake Hazard Earthquakes, ground shaking and liquification are the primary geotechnical constraint to development in Southern California. The nearest known active earthquake faults are the nearby Rose Canyon fault system (approximately 15 miles to the southwest) and the Coronado Bank and Elsinore fault systems which lie approximately 30 miles southwest and 35 miles northeast ofthe site, respectively. The Rose Canyon Fault is considered to be capable of causing a 7.5-magnitude earthquake and considered micro-seismically active, although no significant recent earthquake is known to have occurred on the fault. Investigative work on faults believed to be part of the Rose Canyon Fault Zone, in downtown San Diego and in Rose Canyon, has identified offset Holocene sediments. Confirming that Holocene (geologically recent) displacement has occurred on the Rose Canyon Fault. This indicates that this fault zone, previously considered "potentially active," should now be classified as an "active" fault (reference #10). While the subject parcel would experience moderate to severe ground shaking in the event of a major earthquake, the potential for direct ground rupture in the vicinity of the property is considered extremely unlikely and ground conditions are not conducive to liquefaction. No evidence of other unstable geologic conditions was observed on or adjacent to the property during the site walk. V. REGULATORY AGENCY DATA REVIEW GEI contacted the San Diego County Department of Environmental Health Services and the City of Carisbad Planning Department for information on zoning, past uses and past or present environmental concerns on and adjacent to the property. In addition, a comprehensive review of state, federal and local hazardous material Rancho Milagro Development Job No. 04-8849 Carisbad, California Page 20 usage and disposal databases was performed using the computerized resources of Environmental FirstSearch (EFS) (reference #11). A detailed description of the state, federal and local hazardous materials databases searched by EFS is provided in Appendix C. The locations of any sites identified in the database search are plotted on the quarter mile and one mile radius maps that are also included in Appendix C. Facilities identified in the database review can be divided into two broad categories: 1. Permitted users of hazardous materials, operators of underground or above ground storage tanks, and registered disposers of hazardous waste. 2. Sites listed for unauthorized release of hazardous materials, leaking underground storage tanks, or violation of hazardous materials handling regulations. The subject property is not listed in either of these categories. There is no record of hazardous materials, use, disposal or violation related to the subject property, 5.1 Federal and State Listed Hazardous Waste Sites Federal and state hazardous waste site listings were reviewed for this assessment, e.g., NPL, CERCLIS, NFRAP, LUST, etc. By cross-referencing name, address, and zip code, we conclude that the subject property is not a listed site. The area search for nearby sites listed in these databases identified various sites individually outlined in the Regulatory Agency Data Report Findings included in Appendix C.

Of Toxic Substances Control Phone:(916) 323-3400 The California Department of Toxic Substances Control (DTSC) has developed an electronic database system with information about sites that are known to be contaminated with hazardous substances as well as information on uncharacterized properties where further studies may reveal problems. The Site Mitigation and Brownfields Reuse Program Database (SMBRPD), also known as •CalSites,D is used primarily by DTSCDs staff as an informational tool to evaluate and track activities at properties that may have been affected by the release of hazardous substances. The SMBRPD displays information in six categories. The categories are: 1. CalSites Properties (CS) 2. School Property Evaluation Program Properties (SCH) 3. Voluntary Cleanup Program Properties (VCP) 4. Unconfirmed Properties Needing Further Evaluation (RFE) Please Note: FirstSearch Reports list the above sites as DB Type (STATE). 5. Unconfirmed Properties Referred to toother Local or State Agency (REF) 6. Properties where a No Further Action Determination has been made (NFA) Please Note: FirstSearch Reports list the above sites as DB Type (OTHER). Each Category contains information on properties based upon the type of work taking place at the site. For example, the CalSites database is now one of the six categories within SMPBRD and contains only confirmed sites considered as posing the greatest threat to the public and/or the potential public school sites will be found within the School Property Evaluation Program, and those properties undergoing voluntary investigation and/or cleanup are in the Voluntary Cleanup Program.

CUPA DATABASES DESCRIPTIONS (DB TYPE = US (UNDERGROUND STORAGE TANKS) DEFINITION OF A CUPA: A Certified Unified Program Agency (CUPA) is a local agency that has been certified by the CAL EPA to implement six state environmental programs within the local agency's jurisdiction. These can be a county, city, or JPA (Joint Powers Authority) . This program was established under the amendments to the California Health and Safety Code made by SB 1082 in 1994. A Participating Agency (PA) is a local agency that has been designated by the local CUPA to administer one or more Unified Programs within their jurisdiction on behalf of the CUPA. A Designated Agency (DA) is an agency that has not been certified by the CUPA but is the responsible local agency that would implement the six unified programs until they are certified. Please Note: Track Info Services, LLC collects and maintains information regarding Underground Storage Tanks from majority of the CUPAS and Participating Agencies in the State of California. These agencies typically do not maintain nor release such information on a uniform or consistent schedule; therefor, currency of the data may vary. Please look at the details on a specific site with a UST record in the First Search Report to determine the actual currency date of the record as provided by the relevant agency. Numerous efforts are made on a regular basis to obtain updated records.

Regulatory Standards AB32 in its entirety can be viewed at http://www.arb.ca.gov/cc/ab32/ab32.htm. The pertinent sections of this law are identified below: Section 38560.5 states; (A) On or before June 30, 2007, the state board shall publish and make available to the public a list of discrete early action greenhouse gas emission reduction measures that can be implemented prior to the measures and limits adopted pursuant to Section 38562. (B) On or before January 1, 2010, the state board shall adopt regulations to implement the measures identified on the list published pursuant to subdivision (a). Section 38562 states: (A) On or before January 1, 2011, the state board shall adopt greenhouse gas emission limits and emission reduction measures by regulation to achieve the maximum 10/25/2010 1 1046-03 Rancho Milagro GHG Mr. Jack E.

(B) In adopting regulations pursuant to this section and Part 5 (commencing with Section (38570), to the extent feasible and in furtherance of achieving the statewide greenhouse gas emissions limit, the state board shall do all of the following: (1) Design the regulations, including distribution of emissions allowances where appropriate, in a manner that is equitable, seeks to minimize costs and maximize the total benefits to California, and encourages early action to reduce greenhouse gas emissions. (2) Ensure that activities undertaken to comply with the regulations do not disproportionately impact low-income communities. (3) Ensure that entities that have voluntarily reduced their greenhouse gas emissions prior to the implementation ofthis section receive appropriate credit for early voluntary reductions. (4) Ensure that activities undertaken pursuant to the regulations complement, and do not interfere with, efforts to achieve and maintain federal and state ambient air quality standards and to reduce toxic air contaminant emissions. (5) Consider cost-effectiveness of these regulations. (6) Consider overall societal benefits, including reductions in other air pollutants, diversification of energy sources, and other benefits to the economy, environment, and public health. (7) Minimize the administrative burden of implementing and complying with these regulations. (8) Minimize leakage. (9) Consider the signiticance ofthe contribution of each source or category of sources to statewide emissions of greenhouse gases. a. In furtherance of achieving the statewide greenhouse gas emissions limit, by January 1, 2011, the state board may adopt a regulation that establishes a system of market-based declining annual aggregate emission limits for sources or categories of sources that emit greenhouse gas emissions, applicable from January 1, 2012, to December 31, 2020, inclusive, that the state board determines will achieve the maximum technologically feasible 10/25/2010 2 1046-03 Rancho Milagro GHG Ldn iUMWulfing, Inc Mr. Jack E.

Any regulation adopted by the state board pursuant to this part or Part 5 (commencing with Section 38570) shall ensure all ofthe following: 1. The greenhouse gas emission reductions achieved are real, permanent, quantifiable, verifiable, and enforceable by the state board. 2. For regulations pursuant to Part 5 (commencing with Section 38570), the reduction is In addition to any greenhouse gas emission reduction otherwise required by law or regulation, and any other greenhouse gas emission reduction that othenA/ise would occur. 3. If applicable, the greenhouse gas emission reduction occurs over the same time period and is equivalent in amount to any direct emission reduction required pursuant to this division. The Climate Change Scoping plan lists the discrete early action greenhouse gas emission reduction measures, which will be enforceable January 1, 2010 (Climate Change Scoping Plan - California Air Resource Board - December 2008). The Board adopted nine discrete early action items which identified within the Scoping plan however, none of the discretionary measures relate to the project at hand. The nine measures are identified in Table 1 on the following Page. Additionally, as stated in section 38562-A of AB 32, the state board shall adopt greenhouse gas emission limits and emission reduction measures before January 1, 2011 and enforce these measures starting January 1, 2012. Currently, greenhouse gas emission limits for residential project such as the proposed project, have not been adopted, however. Section 38562-B-3 encourages projects to voluntarily identify greenhouse gas reductions and receive appropriate credit for early voluntary reductions. The California Air Pollution Control Officers Association (CAPCOA) published a white paper which suggested screening criteria of 900 metric tons of GHGs. Jurisdictions such as the County of San Diego, City of San Diego, and County of Riverside have either accepted or adopted these initial screening thresholds. Projects creating more than 900 metric tons of GHGs generally are considered significant and require reduction measures from business as usual with goals ranging from 25% to 33% but would depend on the jurisdiction. 10/25/2010 3 1046-03 Rancho Milagro GHG Mr. Jack E.

For the purposes of analysis, both CH4 and N2O can be converted to an equivalent amount of CO2 (C02e) by multiplying the calculated levels of CH4 and N2O by a Global Warming Potential (GWP). The U.S. Environmental Protection Agency publishes GWPs for various GHGs and reports that the GWP for CH4and N2O is 21 and 310, respectively. C02e emissions generated from the project include vehicular offsite contributions as well as onsite area emissions from combustion activities utilizing natural gas and indirect electricity use. However, the largest source of C02e is produced from the projects vehicular trip generation. The best way to reduce these emission levels would be to reduce vehicular miles traveled, reduce fossil fuel burning vehicles and improve the fuel efficiency of vehicles. 10/25/2010 1046-03 Rancho Milagro GHG Mr. Jack E Henthorn ^OnBtdHnO, InC.

For example, the Energy Independence and Security Act of 2007 will require automakers to boost fleet wide gas mileage averages from the current 25 mpg to 35 mpg by 2020. Project Related Construction Emissions Air quality impacts related to construction will be calculated using the latest URBEMIS2007 air quality model, which was developed by ARB. URBEMIS2007 has been approved by SDAQMD and the City for construction emission calculations. URBEMIS incorporates emission factors from the EMFAC2007 model for on-road vehicle emissions and the OFFROAD2007 model for off-road vehicle emissions. Because CO2 emissions from construction only occur at the beginning of a project, emissions will be averaged over a 30-year period. This recommendation was based on proposals from South Coast Air Quality Management District in 2008. The project engineer expects to have grading complete in approximately two months, trenching complete in ten days, building and paving complete in four months Table 2 below shows the expected timeframes for the construction process at the proposed project location. Utilizing the URBEMIS 2007 model (attached at the end of this report), we find that that total construction emissions during construction of the project will produce 176.66 tons CO2. Given the fact that the total emissions will ultimately contribute to 2020 cumulative levels, it is acceptable to average the total construction emission over a 30 year period which would yield roughly 5.89 tons per year or 5.34 metric tons per year(SCAQMD 2008. A summary of the construction emissions is shown in Table 3 below. 10/25/2010 5 1046-03 Rancho Milagro GHG Mr. Jack E.

Project Related Offsite Vehicular Emissions C02e generated from offsite vehicular sources from the project can be calculated by utilizing the assumption that the average one-way trip distance could be as high as 10-miles and that there could be as many as 190 daily trips. Simply multiplying 190 daily trips by an average 10-mile per trip yields approximately 1,900 miles per day. Multiplying the 1,900 miles per day by 365 days yields 693,500 miles per year. Based on the project vehicle miles traveled, the fleet wide average fuel efficiency of 25 MPG, the project would be expected to burn approximately 27,740 gallons of fuel each day.
