The Stormwater Management Plan that was approved by the Town of Apex on
September 24, 2008 fails to meet the requirements of its local Phase II Program because
no stormwater treatment has been provided for the parking lot adjacent to the stream.
Because of this, the DWQ can not accept the locally approved stormwater management
program as meeting the requirements of the 401 Certification Program. Please submit a
revised stormwater management plan to the DWQ for review and approval that includes
the following items:
A stormwater management plan that removes a minimum of 85 percent TSS and
30 percent TN from the stormwater generated by the entire project (including all
parking areas). For each proposed BMP, please provide a completed BMP
Supplement Form, with all the required items. The BMP Supplement Forms are
available at the following web site: http:/th2o.enr.state.nc.us/su/bmp forms.htm.
2. The Required Items Checklist portion of the Sand Filter Supplement Form, with
all required items attached. In this information, please provide boring data to
show the level of the seasonal high water table (SHWT) within the proposed
footprint of the sand filter. The BMP Manual requires that there be at least a two-
foot separation between the invert of the sand filter and the SHWT. Since the
Sand Filter has been sited adjacent to a wetland, it seems likely that the SHWT is
too high to provide the needed separation. If the SHWT is too high to allow for a
sand filter, then please either relocate the sand filter to higher ground if possible
or provide a more appropriate BMP for an area with a high groundwater table.

Ian, Bill and Mike,
I just spoke with Mike Deaton and he is begging me not to have a poor impression of
Apex's stormwater program.
On this project, Mike Deaton and I agreed that the DWQ will take over the stormwater
management plan review. The updated bullets that are attached reflect that decision.
Thanks,
Annette

I Ian,
The Town of Apex continues to approve inadequate stormwater management plans for
this project. This time the Town actually wrote a letter saying that they
approved the stormwater management plan so the 401 unit should accept it. I have
discussed this with Mike Deaton, the Town Stormwater Engineer, and he has admitted
that the developer wore him down on this one and that the plan he approved DOES
NOT meet Phase II requirements. Mike said that he has conducted all
correspondence on this project via email,and therefore does not have good records
on the applicant's responses to his design questions on the one BMP that they do
have on the property. Mike also offered that I could come to Apex for the day and
"see how things work at a local government. (No thanks!) These comments are
pretty much a copy of the comments made, previously. A case could be made for
returning the project at this point, but I think it might be better to give them
one more chance.
Bill and Mike, I am extremely disappointed in how Apex has handled this project
and I am afraid it might be indicative of their overall stormwater program. If
you are looking for a nearby local government to audit, this might be a good one.
