Pursuant to Water Quality Control Division Policy 1 (Implementation Policy Framework) and 
Water Quality Control Division Procedure 1, the Water Quality Control Division (division) periodically reviews issued policies. Upon a routine review of WQP-20 (Baseline Monitoring Frequency) this year, the division found a few small typographical errors in WQP-20. The division now proposed to correct these errors, as shown in this WQP-20 redline through a minor revision. Procedure 1 §9

The division is now accepting comments upon these proposed minor revisions to WQP-20 and any other typographical errors that should be corrected in WQP-20. Please send any comments to meg.parish@state.co.us. The deadline for comments is October 11, 2021.

Please note that the division does not have the time or resources to more fully re-evaluate the substance of WQP-20 at this time. Any comments that address the substance of WQP-20 will be saved in the division’s files, but not addressed in this minor revision.

A responsive comment period is now open for draft modifications to Permits CO0026638, CO0026409, and CO0032999. If issued, these modifications would require these three large wastewater treatment plants to monitor monthly for a variety of PFAS for two years, along with other requirements.
