Tb.e Division of'OVater Quality (pWQ} reocived your application for a X01 ~'atex Quality Certificgation for
the subject project on Apzil 22; 2005. Mr. tnilatl sohnson oftbuis office has visited the sate and reviewed the
application.. The following informatiozlleomments are needed by this office in Ot'derto complete ourreview:
a} Please pr'o'vide a detailed diagram for the two proposed road crossings and sewer line ~ss~tag far
the development. 'I17e design for the road srmssings should 'include effozts to maintain the base flow
in the stream ehanneL Sills .inside the culvert(s) &nd construction of floodplain benches upstream
and dovvnstreara of the culverts may be required to prev~7,t over widening bf the channel.
An open cut is proposed far the cansizuction of tine sewer line across Goons Creek. To minim+2e .
sediment impacts to the creek (Goose Creek is listed on the State's 303d list as as impaired stream),
directional. b4,~ would be the preferred method of installation. If this is not feasible, please provide
an explanation.
b} The mitigation plan proposes 800 linear ft, of stream restoration for the proposed stream impacts of
654 linear ft. Given, that approximately 3600 linear ft. of Goose Creek runs through the project,
enhancement and/or strea-na sta~on a£tlte entire section of the creek and tributaries is the
recammtmded optipn, lrve~p .tllou~ C~goSe Creek has been channelized istraighte~aed), cattle access
td the creek appears to be the primary"cause of channel instability. 1~emoval oftlie cattle from the
creek, stabilization of ttie banks; and site-specific enhancement of problematic areas along the
channel would probably be more cost effective and provide for greater water quality bernefits.
o) It is noted thPlt 1~ are proposed adjas:enf to the oa-site streaia~s- Please provide the width of
b'uff'ers p~posed aaozag ail streams/creeks (i.e. 50-ft.,100-ft., etc.) throughout the project,
d~ Criven the naxlu~e and size of the proposed project, the stream's classification, and it's listing on the
• State's 303d list of impaired waters, thexe are concerns regei'dztlg cumulative impacts of this project.
Such being the case, it is nrequested thacc you provide a detailed quantitative analysis ("Cumu7ative
Impact Policy" for 401 and Isolated WQtlsnd Progxam) of the potential water quality impacts
assaeiated with the project. DWQ's criteria fox d~t~g the need faz the above noted analysis
are:1) Is growth likely to be induced by the development? 2) Are exisfing uses of the water likely to
be impacted by tlae devclopment4 3) Axe additional regulatory measures needed? 5hoitld yta~t have
question regarding this matter, please contact IvLS, Cgrldi K,aroly at {919) 733-9721. ~~~ ~a
