Project Overview

This project will provide notification of the potential for coal tar contamination, establish a storm water pond inventory schedule, and develop best management practices for treating and cleaning up contaminated sediments. The sampling design includes 15 stormwater ponds, 5 each from residential, commercial, and industrial land use areas. Municipalities in the metro area with MS4 permits of stormwater ponds will be contacted to nominate candidate sites for this study. GPS coordinates will be taken at all sampling sites. Sampling of Stormwater Ponds will be conducted by MPCA Environmental Analysis and Outcomes staff. Chemical Analysis performed: ICP-MS Scan of 18 metals, Mercury, Chloride, Percent Moisture, Carcinogenic PAH's, TOC, SVOC's (including phthalate compounds), PFC's, PBDE's, Pyrethroids, Octyphenols, nonylphenols, and nonylphenols ethoxylates. Parent and alkylated PAH's, Laser Induced Fluorescence-LIF, Black Carbon, and Particle Size.

CLEAN WATER FUND
Sec. 2. Laws 2009, chapter 172, article 2, section 4
(g) $155,000 the first year is to provide
notification of the potential for coal tar
contamination, establish a storm water
pond inventory schedule, and develop best
management practices for treating and
cleaning up contaminated sediments as
required in this article. $490,000
the second year is to provide grants to local
units of government for up to 50 percent of
the costs to implement best management
practices to treat or clean up contaminated
sediments in storm water ponds and other
waters as defined under this article. Local
governments must have adopted an ordinance
for the restricted use of undiluted coal tar
sealants in order to be eligible for a grant,
unless a statewide restriction has been
implemented. A grant awarded under this
paragraph must not exceed $100,000.
