3 EXHIBIT A Phase I Environmental Site Assessment To provide access to personnel from Agency and/or personnel from Stantec Consulting Services Inc. (Stantec) (the environmental consulting firm hired by the Agency) to conduct an inspection of the property in accordance with the Phase I environmental site assessment (ESA) inspection criteria outlined in American Society for Testing and Materials (ASTM) Standard No. E-1527-05. It is anticipated that the property inspection will require 2 to 3 hours of time to complete. Access is required to both indoor and outdoor areas of the property. Photographs of site features will be taken as part of the inspection and included in the Phase I ESA report. To provide a person meeting the definition of either an owner or operator of the facility, and having knowledge of current and/or past operations at the facility, and to make that person available for an interview to be conducted by Agency and/or Stantec personnel as part of the Phase I ESA. The interview is a required standard component of Phase I ESAs and will include general questions regarding past and/or current operations, with an emphasis of practices related to storage and/or use of hazardous materials and/or petroleum products. To review a draft copy of the Phase I ESA report and to provide comments as appropriate to correct or clarify any portions of the report. As the Phase I ESA is being paid for using a Federal Grant, copies of the report may be provided to the U.S. EPA and/or the Minnesota Pollution Control Agency (MPCA) as part of required submittals by the CDA and become public records. One complete electronic copy of the final report will be provided to you for your use upon completion of the final Phase I ESA Report. The Phase I ESA report will be prepared for use by Agency. The Owner may also rely on the report to the extent defined in the Phase I ESA report. Letters of reliance for other parties will not be provided unless specifically agreed to in writing by the Agency and Stantec prior to completion of the Phase I ESA report. Phase II ESA and/or Environmental Site Investigations To provide access to personnel from the Agency and/or personnel from Stantec (the environmental consulting firm hired by the Agency) to conduct environmental assessment sampling activities on the property in accordance with the Phase II ESA criteria outlined in ASTM Standard No. E-1903-97, and/or environmental site investigation activities needed to further define the nature and extent of contamination documented during the Phase II ESA or during investigations conducted previously by others at the property. The specific scope of work for the Phase II ESA or environmental site investigation will be detailed in a Site-Specific Sampling and Analysis Plan (SSSAP) to be prepared by Stantec and submitted to and approved by the U.S. EPA to prior to commencement of on-site sampling activities. An electronic copy of the SSSAP will be provided to Owner concurrently with submittal to U.S. EPA, and generally 5 to 10 workdays before the scheduled start of on-site sampling activities. It is anticipated that the assessment activities will require 2 to 3 days of time to complete. Access is required to both indoor and outdoor areas of the property. Photographs of site features will be taken as part of the inspection and included in the Phase II ESA report. Possible assessment activities could include but are not limited to: Soil Borings – Soil borings will in most instances be performed using a hydraulic probe sampling system or a hollow stem auger drill rig and will be used to collect soil samples from the ground surface to a typical depth of 10 or 20 feet below ground surface. In paved areas, soil borings will typically result in the creation of a 4-inch to 12-inch diameter opening in the concrete or asphalt pavement in order to provide access to the underlying soil. Soil removed from the borings will need to be managed until a determination is made as to whether the soil is contaminated. Borings not completed as monitoring wells will be properly abandoned. Monitoring Wells - ”Permanent” or “temporary” groundwater monitoring wells consisting of 1- or 2-inch ID, Schedule 40 polyvinyl chloride (PVC) casing and screen may be installed in select soil borings. “Permanent” monitoring wells will be completed with a lockable, flush-mount protective cover, and will be installed where: (a) unstable soil or other geologic conditions preclude installation of temporary wells, (b) wells constructed in accordance with MPCA standards are needed to confirm whether previously
