PRP was developed to provide assistance as you investigate, and if necessary, clean up your petroleum release. The MPCA appreciates your timely notification so this Site can be handled in an efficient manner. State laws require that persons legally responsible for storage tank releases notify the MPCA of the release, investigate the extent of the release, and take any necessary actions to clean up the release. A person is generally considered legally responsible for a petroleum tank release if the person owned or operated the tank either during or after the release, unless specifically exempted under law. See Minn. Stat. §115C.021(2012). If development of this property or the surrounding area is planned, State laws require that persons properly manage contaminated soil and/or water uncovered or disturbed even if they are not legally responsible for the storage tank release(s). Developers and other interested parties must also incorporate appropriate response actions to prevent the further spreading of contamination. To receive MPCA review and approval of proposed response actions, please contact the Petroleum Brownfields Program (PBP) at 651-296-6300 or at 1-800-657-3864, or visit their website at http://www.pca.state.mn.us/fovp80a. If petroleum contamination is encountered during development work, the Minnesota State Duty Officer should be notified immediately. The MPCA requests you take steps to investigate, and if necessary, clean up the release in accordance with MPCA guidance documents. The site investigation must fully define the extent and magnitude of the soil and/or groundwater contamination caused by the release. The MPCA recommends you hire a qualified environmental consulting firm to help you investigate and cleanup the contamination on your site. A quali�ed consulting firm should have experience in performing investigations of contaminated sites and in developing and implementing corrective actions. Please be aware that the MPCA does not conduct the investigation or cleanup at your Site. The MPCA provides guidance and technical assistance during the project and reviews the reports submitted by your environmental consultant. However, the MPCA urges you to contact the MPCA project manager whenever you have a question or concern regarding your project. In 1987, the legislature established the Petroleum Tank Release Compensation Fund (Petrofund) to reimburse responsible persons and volunteers (i.e., property owners not responsible for releases) who take corrective action for a portion of their costs. The Petrofund is administered by the Petroleum Tank Release Compensation Board (Petro Board), which is part of the Minnesota Department of Commerce. Mr. Greg Gray Page 2 For petroleum investigations, if you wish to have your costs considered for reimbursement, the environmental consultant you hire must be registered with the Petro Board. A list of registered contractors is available from the Petrofund staff. Please note that, under the Petro Board's rules (See Minn. R. ch. 2890), you must solicit a minimum of two written competitive consultant proposals on a form prescribed by the Petro Board to incur costs eligible for reimbursement and a minimum of two written competitive contractor bids must also be obtained for each contractor service. To learn more about the Petrofund reimbursement program contact Petrofund staff at 651-215-1775 or 1-800-638- 0418 (in greater Minnesota only) or review the information available at the following website at htto://mn.gov/commerce/topics/Petrofund/. Please be aware that Petrofurrd reimbursement determinations are made by Petrofund staff at the Department of Commerce. The determinations are based on whether or not the work performed at a leak site was necessary for investigation and corrective action, which is determined by MPCA staff, and whether or not the costs for that work were reasonable, which is determined by Petrofund staff. Your insurance may cover this release. However, your insurance coverage may be affected by how quickly you notify your provider. Therefore, you should review your insurance plan and contact your insurance carrier immediately after receiving this letter. Please provide notification to the MPCA by submitting the enclosed Leaksite Ownership Form to the MPCA project manager listed below. The Leaksite Ownership Form must be completed and submitted within 30 days of your receipt of this letter to indicate whether you intend to proceed with the requested investigation and/or corrective action. If you do not respond within this time frame, the MPCA.will assume that you do not intend to comply. In this case, the MPCA Commissioner may issue an enforceable or'der that will require you, as responsible party, to take corrective action. Failure to cooperate with the MPCA in a timely manner may result in reduced reimbursement from the Petro Board, see Minn. R. Ch. 2890. If you do not cooperate, the MPCA has the option of taking the corrective actions on your behalf and recovering its costs. If you have questions concerning this letter or need additional information, please contact me at 651- 757-2331 or e-mail andrew.eddy@state.mn.us.

PART II: DATES A. Date release reported to MPCA: May 24, 2013 B. Dates site work performed (tanks removed, piping removed, soil excavation, soil barings, etc.): Work Performed Carlson McCain Inc. (Carlson McCain) and Dean's Tank, Inc. (Deans) personnel were on-site for the removal of one abandoned 1,000-gallon underground storage tank (UST) located at the above referenced apartment property (Site). The removed UST appeared in poor condition, due to surface pitting, rusting and several "dime-sized" holes observed near the bottom of the tank. Photographs #1 through #3, illustrating the Site and the removed UST are attached as Appendix B: Carlson McCain personnel collected a total of six soil samples for on-site field screening purposes. Samples were collected alongside and directly beneath the removed UST. Field screening activities, including visual and olfactory observations, identifed petroleum impacted soil within the former tank basin, directly below the removed UST. Tank bottom samples (B-1 and B-2), collected from directly below each end of the removed UST and within saturated sandy soils, were submitted to a certified laboratory for analysis: It should be noted that a groundwater sample was not collected because of limited groundwater accumulating within the former tank basin. The Minnesota State Duty Of�cer was subsequently notified of a release at the Site (Duty Officer report #134011). The former UST basin, Site characteristics and soil sampling locations are visually depicted on Figure 2, attached. Date May 24, 2013 PART III: SITE AND RELEASE INFORMATION A. Describe the land use and pertinent geographic features within 1,000 feet of the site. (i.e. residential property, industrial, wetlands, etc.) The Site is located at 6341/6342 Highway 65 NE in Fridley, Minnesota. The Site is currently developed as multi-family residential, consisting of an apartment building. The removed UST was located along the east side of the apartment building (Figure 2). The Site is adjoined by mixed residential and light commercial properties to the north; residential homes to the east; light commercial properties to the south; and Highway 65 followed by commercial properties to the west. The nearest surface water is Moore Lake located approximately 1,685 feet (0.32 mile) to the southwest of the Site.

Briefly describe the field screening methods used to distinguish contaminated from uncontaminated soil: Soil samples collected for on-site field screening activities were placed in polyethylene bags. The bag headspace analysis was completed with a MiniRAE photoionization detector (PID) equipped with 10.6 eV lamp. Each bag was half-filled with soil and was closed for a minimum of 10 minutes and then was shaken for 15 seconds before the probe tip was inserted into the bag. The highest meter reading by the PID within �ve seconds was then recorded. The PID was calibrated on-site prior to use with compressed isobutylene gas to read parts-per-million volume/volume of benzene vapors. In addition, visual and olfactory observations were used to determine contaminated from uncontaminated soil. B.

The tank basin soil samples were collected at depths of 10 feet bgs, within saturated, light brown, colored, poorly graded sand (SP). The soil ' sampling locations are visually depicted on Figure 2, attached. The collected soil samples were submitted to Test America, Inc. (Test America) for laboratory analysis of benzene, toluene, ethylbenzene, xylenes (BTEX) and diesel range organics (DRO). ' , ' ' To minimize cross contamination of samples, clean disposable gloves and sampling utensils were used while obtaining samples for analytical testing. Soil samples were collected in laboratory-supplied, test-specific sample containers, then stored and shipped in ice-filled containers along with their chain of custody form until they were relinquished to the laboratory.

If no further action is necessary, the MPCA staff will review this report following notificat0l ion of soil treatment. , Carlson McCain recommends a standard scope of work LSI, which would include the advancement of up to five direct push soil borings within and around the former tank basin (source area) to assess the vertical and horizontal extent of soil and groundwater contamination. ' In addition, soil gas samples should be collected at the depth of the Site building's and surrounding properties basement footings to evaluate the potential for vapor intrusion to the Site apartment building and nearby residential homes. Subsequent investigation reporting would follow. � ' i The petroleum release appears to be the result of UST corrosion. Pitting and several "dime-sized" holes were observed near the bottom of the removed UST. The UST has been out of service since the conversion to natural gas .in the 1970's. Field screening activities and laboratory analysis of soil samples collected below each end of the removed UST identified petroleum impacts to native, saturated sandy soil encountered below the tank. Laboratory analysis of tank bottom soil samples B-1 (10') and B-2 (10') indicated DRO and ethylbenzene concentrations above laboratory detection i�m,ts. Based on an evaluation of the potential threats as they relate to the petroleum constituent ' concentrations detected within soil samples B-1 (10') and B-2 (10'), petroleum impacted soil in contact with shallow groundwater and confirmatory information regarding the MPCA general policy, a standard scope LSI is recommended: , ' ' ' ' Impacted groundwater tlzat /:as or may affect human Izealtlt: Shallow groundwater was encountered during tank removal activities. Saturated sandy soil was encountered at an approximate depth of 10 feet bgs. Because impacted soil appears in contact with the shallow groundwater table, an LSI is necessary to evaluate and potentially define the extent of groundwater contamination. Led or ntay lead to dangerous conditions due to petroleum vapor: The potential for vapor intrusion to the Site building (apartment complex) may currently exist. Moderate concentrations of DRO were detected in soil samples collected below the removed UST, located along the east side of the Site apartment building. Therefore, Carlson McCain recommends soil gas samples be collected within the vicinity of the former UST basin, towards the Site building and toward adjoining residential properties to assess potential vapor intrusion impacts. • Affect or may affect surface water quality: The threat for surface water impacts are ' considered low due to the distance between the former tank basin and nearby surface water features. The nearest surface water is Moore Lake located approximately 1,685 feet (0.32 mile) to the southwest of the Site. The concentrations of petroleum � constituents detected in soil below the removed UST is likely insufficient to migrate a distance that would impact nearby surface waters. However, the vertical and horizontal extent of contamination is unknown.

Based on Site conditions with respect to MPCA general Guidance, Carlson McCain recommends the standard scope of work LSI be completed to assess the vertical and horizontal extents of petroleum impacts discovered during abandoned UST removal activities.
