Carrollo Divisional Inspector Northern Division TO: Valdas V Adamkus . Regional Administrator Region 5 We visited the Better Brite Zinc Shop Superfund removal site located in DePere, Wisconsin to perform an unannounced site review. We were at the site from February 26 to February 28, 1990. At the time of our visit,-the site was inactive because it was a "potential responsible party" (PRP) site and the consent order had not been approved. During our site visit, we observed a former shop employee entering the site. When talking to EPA officials about this situation, we were informed that EPA was not in control of this site at the time. Therefore, the PRP had access to the site and apparently could let others onto the site at its discretion. We also observed children playing at the site. Part of the removal action included removing contaminated soil. There were no fences or ropes controlling access to the contaminated soil. The on-scene coordinator said that the.concentration of con- taminants did not warrant fencing. The Agency for Toxic Sub- stances and Disease Registry is re-evaluating the data to deter- mine the extent of any possible public health risk. A removal was warranted at the zinc shop because the condi- tions at the site met the criteria in the National Contingency Plan (NCP), 40 CFR 300.65. The NCP states that if a removal action is appropriate, actions shall begin as soon as possible to prevent, minimize, or mitigate the threat to public health or welfare or the environment. The NCP provides a list of removal actions which may be appropriate in some situations. One pos- sible removal action is to put fences, warning signs, or other security or site control precautions where humans or animals have access to the contaminant. o HEADQUARTERS LIBRARY ENVIRONMENTAL PROTECTION AGENCY WASHINGTON, D.C. 20460 ------- Recommenda t ion Our observations of the man entering, and the children playing at the site show that there is unrestricted access to the site. Therefore, we recommend that Region 5 consider posting warning signs at this site to alert the public of the potential for health risk. . . Action Required In accordance with EPA Directive 2750, the action official is required to provide this office with a written response to this report within 90 days of the report date. • If you have any questions, please contact me or Michael Rickey.
