• WET testing in A(1) updated to say "Monitor & Report" per 2012 WTP strategy

• Removed flow footnote about log books per 2012 WTP strategy (continuous
discharge so not needed)
• Map indicating instream sampling locations has been included (inadvertently left
out in draft)
• Monitoring frequency has been changed from 2/month to monthly for turbidity,
salinity, conductivity, dissolved oxygen, and total dissolved solids per 2009 WTP
strategy; monitoring was mistakenly changed to 2/month in the draft permit (see
comments below)
• Monitoring for temperature removed per 2012 WTP guidance
• Monitoring for arsenic has been removed after permit file review; inadvertently
added to draft (see comments below)
Comments from WaRO (received 6/15/17 via phone)

has been updated in the final permit.
o Temperature monitoring has been removed per 2012 WTP guidance
Comments from Dennis Crane (ORC) (received 6/21/17 via phone)
• Comment received after 30-day public notice comment period (30 days ended
6/20/17)
• Requested if there was any way to remove arsenic monitoring, as to his
knowledge there has never been any found in test wells or the raw water analysis
o A review of the file history indicates that the effluent limitation and
monitoring for total arsenic was removed from the permit in 2006 as an RPA
revealed no potential to exceed the allowable concentrations for the
discharge.
o DWR Response: After review of the permit file, monitoring for total arsenic
has been removed from this final permit as it was previously determined that
arsenic did not have a potential to exceed water quality standards.

Brianna,
Sorry, both our scanners are currently down, but the map I wanted to attach was simply the second map located in the
expired 2007 permit noting the discharge point and the two stream sample locations B and M6. (This second map was
simply not in the .pdf copy of the new Draft permit we received.)

Brianna,
I've reviewed the draft permit for Tyrrell Co. RO WTP, N00086924 and everything looks good. The attached instream
monitoring map (noted in A(4)) was not attached, but I assume it's the same as in the previous 2007 permit?
Thanks,
