Thank you for reaching out Maria.
Thank you for sending those links in the email. We have started a separate maintenance log for BMP 236 as you have recommended. Also, we have started our turbidimeter log for everytime we need to sample in the future.
1) Yes we have reviewed BMP 236 and have been following its maintenance guidelines as well as conditions of use as detailed out in the SWMMWW. Attached is a picture displaying the use of BMP 236.
"Vegetative filtration as a BMP is used in conjunction with detention storage in the form of portable tanks or BMP C241: Sediment Pond (Temporary), BMP C206: Level Spreader, and a pumping system with surface intake. Vegetative filtration improves turbidity levels of stormwater discharges by filtering runoff through existing vegetation where undisturbed forest floor duff layer or established lawn with thatch layer are present. Vegetative filtration can also be used to infiltrate dewatering waste from foundations, vaults, and trenches as long as runoff does not occur."
- For every five acres of disturbed soil use one acre of grass field, farm pasture, or wooded area. Reduce or increase this area depending on project size, ground water table height, and other site conditions.
- Wetlands shall not be used for vegetative filtration.
- Do not use this BMP in areas with a high groundwater table, or in areas that will have a high seasonal groundwater table during the use of this BMP.
- This BMP may be less effective on soils that prevent the infiltration of the water, such as hard till.
- Using other effective source control measures throughout a construction site will prevent the generation of additional highly turbid water and may reduce the time period or area needed for this BMP.
- Stop distributing water into the vegetated filtration area if standing water or erosion results.
2) We have reviewed BMP 250 and 251 and have been communicating with Rick Fuller from Trendline Environmental about the chemical treatment options, where our discharge point will be located and so forth.
3) I have reviewed the new permit and have printed it out to bring to the job shack located onsite at Stetson Heights. (thank you for the link)
Thank you for coming out to site Maria this week. If you need any additional information please let me know.
All the best,
Robert Terhune

Hi WAR306103 Stetson Heights Team:
This is the current CSWGP Compliance Inspector for WAR306103 Stetson Heights, Maria Zeman, checking back in because I have not heard back of any progress on things we have been discussing the last few weeks. Thank you for reaching out to me December 28, 2020 about treatment options for turbid pond water. Thank you for being able to meet with me on your project site this Tuesday, January 12, 2021.
Have you followed my coworkers advice on how to submit the required items requested (including reviewing BMP 250 & 251) to be able to review treatment request for approval? As well as reviewing maintenance requirements for BMP 236?
https://fortress.wa.gov/ecy/ezshare/wq/Permits/Flare/2019SWMMWW/2019SWMMWW.htm
Have you found a CESF treatment operator?
Have you decided where you will locate this chemical treatment discharge point?
Also, have you taken time to review your current permit and have a copy available to reference in your job shack? As well as a copy of your new Coverage Letter ?

Thank you for understanding that per your CSWGP, “Ecology presumes that a Permittee complies with water quality standards”, “must fully: comply with all permit conditions”, and “implement stormwater BMPs”, “and maintenance” (S3 pages 9-10).
Thank you for continuing to work with Ecology to get back into compliance with your CSWGP and making efforts to protect water quality.

PS I included your Permit Administrator, Miya Spratt, on this email who can process a Modification Form for your permit to add more than 1 Discharge Point from that date forward, if you were unable to figure out how to do it yourself when updating DMRs. This will then be modified to reflect in PARIS (a publicly searchable database of Ecology) and in your DMRs. I have confirmed that you cannot back date and correct this. Unfortunately, you have been reporting to Ecology only 1 point of discharge to-date.

PSS Have you begun an operation and maintenance log for BMP 236? As-well-as calibration records for your turbidity monitoring equipment?

Grant:
I am unable to authorize use of chemical treatment for this project at this time.
You did not identify where you will dispose of the treated water, you have not indicated that you will filter and monitor the water prior to discharge, and you do not have a certified CESF treatment operator listed on your request.
Please review BMPs C250 and C251 in the 2019 Stormwater Management Manual for Western Washington for chemical treatment guidance.
Please provide me with the appropriate answers and I will process your request.
