A Site-Specific Phosphorus Criterion Proposal for reducing the phosphorus level in Lac Courte Oreilles to 10 parts per billion was developed by LimnoTech, an independent water environment research and engineering firm that regularly assists federal and state agencies, including the WDNR, to develop plans to restore and protect lakes and streams across the country. Submitted with the SSPC, COLA also submitted a request that the WDNR initiate emergency rulemaking within 60 days of receipt of the Site Specific Phosphorus Criterion proposal.
