Question Regarding Dewatering Permit at VCP Site

Hi Diedre,
My name is Allison, I work with Bill Rees in the VCP. I am working on a remedial action plan for a site that has
groundwater impacts above the MCL. They have a section in the report that discusses the potential need for construction
dewatering. The site is less than an acre and groundwater could be encountered through hotspot removal (stripping the
entire site down to native is not anticipated). I've included the text from the RAP that discusses dewatering below.
"Based on the planned building design, significant construction dewatering is not anticipated. In limited locations
where dewatering is required all dewatering water will be containerized (e.g., using a frac-tank or equivalent) and
characterized for management at an off-site disposal facility."
I am reaching out regarding what kind of permit, if any, would be required for this (UPDES, Construction, etc.). We have
had previous conversations with them about the need to obtain a permit for dewatering, but I wasn't sure if a permit would
be needed based on the limited scope and their proposal to manage that water at an off-site disposal facility, rather than
discharging it to nearby surface water.
Please let me know if you have any thoughts on this. I am also happy to discuss over the phone. My number is 385-391-
8134. Since obtaining permits do that time, I would like to have an answer for them as soon as possible.
Thanks for your help!
Allison

Hi Allison,
Thanks for reaching out. Based on what you've indicated, it doesn't sound like a permit would be required since they are
planning on total containment. If they change the plan, permit(s) may be required. I've looped in others in case I'm missing
something.

Allison,
Thanks for reaching out to DWQ. Deidre is correct that if the dewatering water is containerized and disposed of off site, a
discharge permit is not required. If the situation changes and the operator wants to dispose of the water to storm drain or
water of the state, either a Construction Dewatering and Hydrostatic Testing Permit (UTG070000) or Treated
Groundwater and Surface Water Permit (UTG790000) would be required. Given groundwater contamination history, the
water would need to be tested for the conditions of the Treated GW/SW permit to determine which permit is applicable.
The permit authorization process takes about 2 weeks following submission of a complete Notice of Intent (NOI). Please
feel free to reach out if we can provide additional information.
