(AMEC) in December 2011 and early January 2012. The subject property is currently owned by Magellan Pipeline Company LP (Magellan). It is understood that El Paso Electric Company (EPE) intends to acquire the property for future development. This Phase I ESA was performed in general accordance with the scope and limitations of the American Society for Testing and Materials (ASTM) Standard Practice E 1527-05. The purpose of this assessment was to evaluate whether evidence exists to suggest that hazardous/regulated materials or adverse environmental conditions are, or may be, present at the surface, in the subsurface, or in groundwater beneath the site. The scope of work performed included research and review of publicly available records and information concerning the history of site development, the geologic and hydrogeologic setting, and environmental regulatory agency activities in the area. A reconnaissance was performed to observe and record pertinent data concerning current local conditions and interviews with persons knowledgeable of the site were conducted. The findings of this Phase I ESA indicate that the subject site is primarily undeveloped lands with the exception of petroleum pipeline easements crossing the southern end of the parcel. Pipeline easements also exist immediately north and west of the property line. The property is bound to the south and west by Magellan’s El Paso Terminal. Land to the east is relatively undeveloped land, as is land north of the pipeline easement, portions of which owned by the Department of Defense (DOD). Illegal dumping was observed across the site, primarily along unpaved roadways at the northern end of the site and a main north-south trending road crossing the central portion of the site. Debris observed includes tires, construction debris and residential waste, although minor areas of hydrocarbon staining and paints were also observed. Some historic site grading was noted on and near the pipeline easements and at the southwestern corner of the site near the Magellan facility. During the reconnaissance a 1 to 1-1/2 inch metal pipe was identified which runs north-south for several hundred feet near the eastern property boundary. Evidence of ground disturbance in this area was also noted in aerial photographs reviewed. The line is believed to be a historic water line, now abandoned. A series of culverts exist near the fence line bordering the Magallen facility yard on the western boundary of the southern half of the site. These culverts lead into a drainage ditch and low area located on the site (within the area occupied by pipeline easements). No direct evidence of impacts emanating from this area were noted, however, baseline sampling was recommended to evaluate the potential for runoff from the Magallen yard. No impacts were identified. It is Exhibit RC-4B Page 4 of 534 AMEC Ref No. 1167171140 Phase I Environmental Site Assessment 75 Acre Magallen Parcel, El Paso, Texas Page (ii) recommended protective measures be implemented to minimize the potential for future impacts to affect this area. Review of available data from regulatory agencies indicated that the subject site does not appear on any of the researched regulatory agencies records. No sites listed under NPL, delisted NPL, proposed NPL, NPL liens, CERCLIS, CERCLIS- NFRAP, RCRA CORRACTS, RCRA TSD, RCRA LQG, RCRA CESQG, ERNS, INST/ENG Controls, or FINDS facilities were identified within the applicable ASTM search radii. A RCRA SQG (Small Quantity Generator) listed as Safety-Kleen Systems, located at 4050 Flagger Street was noted at a location approximately 1/8 mile east of the site. No know violations from this facility were identified. In addition, a RCRA-No Gen (a facility that does not presently generate wastes, but was otherwise listed), was identified. This facility, Clean America of Texas Inc, is located at 13901 Montana about ¼ mile east of the site. This facility does not generate wastes but has been cited for past transportation and record keeping violations. No reports of a release at either facility were noted. Our review of available data from regulatory federal agencies concerning the El Paso Terminal (Magellan) facility located at 13551 Montana Avenue in El Paso Texas is also listed as a RCRA- NonGen (TXR000049304). Available records also showed the site being listed as a RCRA- LQG facility during 2002, 2004 and 2008. In May 21, 2009 the El Paso Terminal changed its status to RCRA-NonGen. Several violations were noted in the database yet these were categorized as minor or moderate and appear to have been resolved in a timely manner. The Texas Commission on Environmental Quality (TCEQ) records reviewed for the El Paso Terminal showed the facility currently conducting remediation activities under the IHW Corrective Action Program. An Affected Property Assessment Report (APAR) was submitted by Magellan Midstream Partners, L.P. on December 9, 2010. Based on the review of the limited portions of the APAR provided to AMEC, the chemicals of concern (COC) concentrations did not exceed the critical commercial/industrial Protective Concentration Levels (PCLs) developed for the affected property. It was recommended by the Magellan consultant that an institutional control be filed within the real property records of the El Paso County restricting the affected property land use to commercial/industrial, and no further response actions would be required. TCEQ sent a Notice of Deficiency (NOD) to Magellan on March 4, 2011 stating that additional assessment was required in order to vertically delineate down to the Method Quantitation Limit (MQL) and that groundwater assessment may be required. A response to the comments addressed in the NOD was generated by Zephyr Environmental on March 10, 2011. In this response, Zephyr states that it believed vertical delineation was achieved since borings extended below the target depth in borings placed in close proximity to the impacted zone. The TCEQ responded on May 19, 2011 with a letter stating that they do not concur with Zephyr’s conclusion and directed additional vertical delineation sampling to be conducted. An October 28, 2011 letter from Zephyr discusses a July 1, 2011 meeting in which the TCEQ appears to have approved the APAR as submitted without additional assessment, with the provision that a deed notice would be generated for the release. No additional documentation confirming whether the TCEQ has approved the APAR or deed recordation was received. Exhibit RC-4B Page 5 of 534 AMEC Ref No. 1167171140 Phase I Environmental Site Assessment 75 Acre Magallen Parcel, El Paso, Texas Page (iii) No State Superfund, SWL/LF, VCP, current or historic SPILLS, or MSD facilities were listed within the applicable ASTM search radii. Additionally, no State listed institutional or engineering controls, or AULs Liens were listed for properties within a ½-mile radius of the subject property. The Flying J Travel Center facility located at 13551 Montana Avenue, approximately 1/8 to the west of the subject property is equipped with one 12,000-gallon gasoline UST and three 20,000- gallon diesel USTs. The Super Stop convenience store (13900 A Montana Avenue) is listed on the UST (underground storage tank) database. According to the database records reviewed, this site has one 20,000 gallon gasoline tank of single wall fiberglass reinforced plastic construction. Neither facility was identified as having a release and based on the available information are not considered to represent a recognized environmental condition to the subject site at this time. Petroleum pipeline easements exist on the northern and western margin of the site and lines cross the southern half of the site. No reported releases were identified during our review of available databases or during our interviews with Magellan personnel. No surficial evidence of releases was identified. Limited evaluation of subsurface conditions during a concurrent Phase II ESA did not identify evidence of a release.
