 Where a parameter was 1998 303(d) listed, the priority for TMDL development is the year provided and is assigned based on the consent decree schedule.

 Where a parameter was only identified as impaired under the IWR, a priority of “medium” was assigned. Exceptions are waters where the impairment poses a threat to potable water or 

 human health, which have been assigned a “high” priority, and fecal coliform impairments, which have been assigned a “low” priority. All other listings as of this cycle are prioritized based

 on the following: it is the Department's intent that listings with a "High" priority be addressed within the next 5 years, listings with a "Medium" priority be addressed within 5-10 years as resources allow,

 and listings with a "Low" priority be addressed within the next 10 years.
