<br />~ <br />~HILLS <br /> <br />TCAAP Community Dialogue: Environmental Clean-up Focus <br />July 10, 2002 <br />7:00 p.m. <br /> <br />. <br /> <br />Dialogue Notes Prepared by the City of Arden Hills <br /> <br />Question: Are the development options currently being proposed consistent with the Vento Plan <br />in regard to the amount of open space? <br />These meetings are the preliminary meetings to begin the planning process. It is always <br />the City's intention to use the Vento Plan as the framework for the planning process. <br /> <br />Question: Where in the "pecking order" of excessing property to the City? <br />GSA is not here to answer the question; therefore, it will be put on the city's web at a <br />later date with an answer after GSA can be eontaeted. <br /> <br />Question: To what levels have PCB's been cleaned up and have they been identified as high <br />occupancy or low occupancy levels? <br />That is a very technical question which requires the actual teehnical data which is not <br />available at this meeting so speeifie levels eannot be noted. Again, this item will be <br />addressed on the website when an answer ean be obtained. <br /> <br />Question: How many known contaminated sites are in the proposed acquisition area by Arden <br />Hills? <br />The main sites are sites listed as Sites I, K, C, 0, Primerffracer Area 135, and 129-3. <br />These identified areas can be found on the slide presented during Mike Fix's presentation <br />entitled Cleanup Sites. Please also see the Installation Action Plan for further information <br />on these sites on the Army's website. This link will be made available through the Arden <br />Hills website. <br /> <br />. <br /> <br />Question: Is it correct to assume that cleanup standards would be higher for residential use and <br />lower for park use? <br />The general cleanup standard the state falls back on is 400 ppm for lead for residential <br />and recreational use and 700 ppm for lead for industrial use. The MPCA on occasion will <br />go higher or lower depending on site-specific conditions. There are also cleanup <br />standards written into law such as the drinking water standard which must be met. There <br />are very few legislative standards for acceptable cleanup levels in soil. A risk assessment <br />is generally used to determine such standards. Cleanup levels can be set for a property <br />when the future use is determined. <br /> <br />Question: Will the planned residential development on TCAAP require more pollution litigation <br />planning? <br />The Army has indicated that it will cleanup the site to negotiated industrial standard. If <br />residential uses were planned, then additional cleanup might be required. <br /> <br />. <br /> <br />Page 3 of 5 <br />
