Preston Howard, Jr., P.E., Director 1 ? • NCDENR NORTH CAROLINA DEPARTMENT OF ENVIRONMENT AND NATURAL RESOURCES June 1, 1998 Henderson County DWQ Project # 980169 APPROVAL of 401 Water Quality Certification and ADDITIONAL CONDITIONS Mr. Norton Segal S & N Properties, Inc. 500 Crooked Creek Lane Hendersonville, NC 28739 Dear Mr. Segal: . You have our approval, in accordance with the attached conditions and those listed below, to place fill material in 318 linear feet of waters for the purpose. of constructing roads at the Triple Creek subdivision in Henderson County, as you described in your revised application dated May 14, 1998 and original application dated February 19, 1998. After reviewing your application, we have decided that this fill is covered by General Water Quality Certification Number 3108. This certification allows you to use Nationwide Permit Number 26 when the Corps of Engineers issues it. In addition, you should get any other federal, state or local permits before you go ahead with your project including (but not limited to) Sediment and Erosion Control, Coastal Stormwater, Non- Discharge and Water Supply Watershed regulations. This approval will expire when the accompanying 404 or CAMA permit expires unless otherwise specified in the General Certification. This approval is only valid for the purpose and design that you described in your application except as modified below. If you change your project, you must notify us and you may be required to send us a new application for a new certification. If the property is sold, the new owner must be given a copy of this Certification and approval letter and is thereby responsible for complying with all conditions. If total wetland fills for this project (now or in the future) exceed one acre, compensatory mitigation may be required as described in 15A NCAC 2H .0506 (h). For this approval to be valid, you must follow the conditions listed in the attached certification and any additional conditions listed below. 1. Deed notifications or similar mechanisms shall be placed in all lots with remaining jurisdictional wetlands and waters to restrict future wetand and/or water impact. These mechanisms shall be put in place within 30 days of the date of this letter or the issuance of the 404 Permit (whichever is later). This letter completes the review of the Division of Water Quality under Section 401 of the Clean Water Act. If you have any questions, please telephone John Domey at 919-733-1786. Pne +!

The option of constructing a bridge seems reasonable to avoid mitigation at first glance. However, the va..t majority of our roadway projects in new subdivisions are designed to meet NCDOT requirements. NCDOT does not like nor want more bridges so the policy creates a dilemma for the developer (private roads or public roads with mitigat:.on). The construction of a bridge will require significant disturbance to the stream banks. In fact, we believe that floodwaters will likely erode the stream banks at the bridge abutments ere€iting essentially the same situation as a culvert pipe, 4. Why can't a pond creation be used to mitigate a stream impact? If a pond creates an extensive shore line, it seems to us that the situation is at least the same, Rs the stream - it certainly has riot degraded the environment for aquatic life. It is just a matter of time before someone challenges this policy. Do you have scientific data to back this policy? 111. MITIGATION TECHNIQUES No comments IV. CUMULATIVE IMPACT 1. The policy clearly refers to the cumulative -impact on a panic lar stream. In our recent application for the Triple Creek Subdivision, it is our opinion that there are four (4) separate streams involved in the project (see attached sketch map). There should be no mitigation required because each stream is impacted less than 150 feet. 2. If the DWQ takes the poiition that these four (4) crossings impact the same stream, we feel that the private sector will suffer a tremendous financial impact by this policy which will effectively stop all new development. This will no doubt be challenged by someone in the court system. It seems to us that a stream should be defined as a watercourse clearly identified by "name" on the USGS quad sheet. Any other creek with a positive 7Qlo flow would be considered a "tributary" to a "stream," and subject to the 150 foot limit. (Each tributary would be a separate case.) We thank you for giving us the opportunity to comment on this policy. If you have any questions or concerns about our suggestions, please feel free to call on Tom Jones or me. William G. LaNley, P WGL/ec DwQ rules fcr pern,4tting of stream fill also reauire consideration or cumulative impacts (15A NCAC 2H .0506 (b)(S)) This decision is espec=ally important in linear or phased prc;ects. _- te=.,s cf streams, if n articular s rr ...m with J positive 7Q10 or 30Q2 flow or with vertebrate aauatic life is planned to he impacted by fill (i.e., hardening or culverc_ng) greater that. 150 feet, then mitigation will be required for the entire length includinC the 150 feet. Relocated streams which have these characteristics will be reauired to follow stream relocation guidelines. Past impacts which reau?reo A-04/401 authoriZaticn w_!-1 be considered when additlcna> >:-,pacts are planned in order to control cumulative impacts. Several pCSS, ble scenarios are snGf- on the attached sketch for illustrative purposes anc are discussed below. if multiple crossings of a particular stream are planned and the stream r:eets the flow/biotic criteria outlined afove, then ream mitigation will be reauired if the total fill for that st exceeds 150 feet. Mitication would be reauired for the entire amount of impact to the stream. _xcept as note,4 a^OVe, mitiaati^n reaui reorients will be considered separately _or each stream. For instance if fill for each separate (culverti ng) in a particular projec: _s less than 150 fee- , tiler- r. stream mitigation will P_Ct be t=aut== . _Or the proj iec-.unlesstotal fill of the stream exceeds 150 cue to multiple cross?nc? of the same stream. If a strec..T'i with positive 7Q10/30Q2 flow or vertebrate F.auatic lif= is straightened using bioengineering techniauTes, any loss of stream length greater than 150 feet will require mitigation. If biceng_::eering techniques are not used (for insta ce i? the stream is placed 4, a concrete lined convevance), then the entire length would reauire compensatory mitigation if the langth exceeds 150 feet. `gain, bridging of streams will not requ'ir'e compensatorv mitigation for the stream impacts since the aauatic life use is still present beneath the bridge. in addition, compensatory mitigation for wetland impacts may be required in accordance with 15A NCAC 2H .0506 (h). These procedures are outlined in separate DWQ policies. streampol.mem x POSSIBLE STREAM COMPENSATORY MITIGATION SCENARIOS Division of Water Quality, Environmental Sciences Branch October 2, 1997 2SO foot crossing - need 2:1 mitigation for entire 2S0 foot loss stream 150 foot crossing no compensatory mitigation needed stream styessm three 100 foot crossings (300 feet total) - compensatory mitigation at 2:1 ratio needed for 300 feet of impact since total stream crossings exceed 150 feet I slope Relocated stream - if loss ((old stream (Lo) length minus new stream (Ln) length)) is greater than 150 feet, then compensatory mitigation at 1:1 ratio needed for difference as long as bioengineering techniques are used to relocate the stream.

These policies have been reviewed and field-tested by DWQ Regional and Central Office staff over the past several months. These policies are intended to clarify our 401 Water Quality Certification rules, namely 15A NCAC 2H .0506 (b) and (c) as they relate to mitigation requirements for impact to streams and ponds. Please provide any comments to John Dorney by 17 April 1997 at 4401 Reedy Creek Road, Raleigh, NC 27607 (919-733-1786). In the interim, DWQ staff will continue to utilize these policies in our decisions for the 401 Water Quality Certification program. We will also mail copies of this draft policy to everyone on our 401 Water Quality Certification mailing list with a forthcoming notice about revised General Certifications and Neuse River buffer rules.

However unlike wetlands, the rules do not provide numerical guidelines for compensatory mitigation regarding impacts to streams. The Division of Water Quality (DWQ) intends to work with-Department of Transportation (DOT), NC Wildlife Resources Commission (WRC), US Army Corps of Engineers (COE), other agencies and the private sector to develop and refine gL'idell:l.c'S for Compensatory mitlgatlon for unavoidable 1'aC?S Co streams. These decisions will be re_-ected in appropriate General Certifications, concurrence letters for General Certifications and Individual C=rz4"cations for the 401 Water Quality Certification Program. -Listed below is DWQ's policy developed to implement this rule. We fully expect that work in this area will involve additional discussion and related. fieldwork. if this policy changes, we will notify our 401 Certif-ication mailing list o= those changes. This mitigation pollcv applies to decis-- s made by the 401 Water Quality Certification program in acccrcance with i 5A NCAC 2H .05006 (b) Atte_nots have -Jeen made to coordinate ool_CV with the U.S. Army Corps or E%^ineer-s. However i_ must be recognized that stream mitigation policies of COE and DWQ may be dif=event at times as a result of t d1_.erent mandates of these agencies. I. DWQ-Notification and Distance Biological data (primarily benthic macroinvertebrate analvsis) indicate that streams in culverts are biologically impaired - that 1S, the aauatlc life use is degraded or lost. Culverti ng or otherwise burying streams should be minimized _:. order to protect these aquatic life uses. A linear distance of 150 feet seems to provide a reasonable balance between roadway design criteria (allowing a four lane road with median and side slopes), site design and DWQ staff workload. For the sake of consistency, this distance will also apply to all projects which propose to impact channels whether the project is linear (e.g., roads) or not (e.g., land development). This provision is a reporting threshold for all projects eligible for Nationwide Permit 26 as well as other Nationwide and Regional (General) 0 Permits which require written concurrence from DWQ and is listed as appropriate in the accompanying General Certification. For notification purposes, any time more than 150 feet of stream is proposed to be impacted by the entire project (not just necessarily in one location on that project), then notification to DWQ will be required. Applicants will be required to separately report the length of each stream crossing in the project. Finally if notification is required to DWQ, staff may add site specific conditions (such as a requirement for stormwater ponds for commercial or industrial projects) as allowed by the appropriate General Certification and the associated Yule under 15A NCAC 2H .0500. Streams are linear rather than areal features. Therefore streams (according to 1:,A NCAC 2H .0506 (b)) are defined as intermittent or perennial jurisdictional waters (i.e., non-wetlands) as designated by the US Army Corps of Engineers whether or not they count toward the 500 linear-foot threshold provision for Individual Permits. II. Mitigation Requirements Compensatory mitigation must replace those unavoidably lost or degraded existing aquatic life uses of these streams either through instream measures and/or riparian techniques such as buffer establishment and tree planting for temperature control. In this regard, only loss or degradation of streams with existing aquatic life uses will require mitigation by DWQ rules. For the purposes of this policy, stream mitigation will be required for streams which meet one of the following criteria: 1. a positive 7Q10 or 30Q2 flow, or 2. where aquatic vertebrates are present which require continuous water (such as fish, crayfish, clams/mussels or bullfrog tadpoles (who usually require at least two years to mature]). Streams meeting these biological criteria would be identified from a field visit by applicants, their consulcancs or DWQ staff for those streams with watersheds smaller than those predicted to have poa Live 7Q10/30Q2 flow. DWQ staff will only 'make a site visit for a 401 Certification decision after (or simultaneously when) the COE has determined that the streams are jurisdictional waters. This definition of streams requiring compensatory mitigation is consistent with decisions made by the DWQ's NPDES program. This statistic can be readily calculated using methods developed by the U.S. Geological Survey as described in "Low-Flow Characteristics of Streams in North Carolina", 1003, USGS Water- Supply Paper 2403 by G.L. Giese and R. R. Mason, Jr. Streams that do not meet the flow or aquatic life requirements outlined above would not require stream mitigation by DWQ. If a stream has no existing aquatic life use (per 15A ? A NC_`-_C 2B .0202(27)) due to existing watershed conditions'or historic impact, then stream mitigation would not be required. This distinction is important since DKQ rules state that uses attained cn or after November 25, 1975 shall be protected. Any stream supporting aquatic life (present in a "significant and not incidental manner") is classified as Class C or SC and must be protected to maintain C or SC uses. Furthermore, the existing use definition (15A NCP_C 2B .0202 (27)) states that uses shall be deemed attainable if the uses can be achieved through implementation of reasonable Best Management Practices (BMPs). DWQ urges applicants to install these BMPs to maintain the existing uses of the water. For instance, applicants are reminded that bridges are encouraged as a means to avoid the need for stream mitigation. if an applicant believes that the stream in question does not have an existing aquatic life use even though the 7Q 10 or 30Q2 are greater than zero, then the applicant may collect data (vertebrate and macrobenthos data) to present to DWQ to document that situation. The studv deli do and analy i ca me`nodoloay mus t; writ ..n ax rovai by DWO b=-?Y= -t-on is under ake Unless these data are provided, streams with positive 7Q10 or 30Q 2 flow will be assumed to have existing aquatic !- use. 'z is clear that streams which are predicted to have either zero flcw 7Q10 or zero glow 30Q2 can have existing aquatic life uses depending primarily on the flow duration.. Until the relationship of the presence and extent of aquatic life in these streams is better understood, DWQ will not require compensatory mitigation for the cul:Terting of these streams unless vertebrate aquatic life is present. However applicants will be encouraged to follow stream relocation guidelines were feasible for these streams When compensatory stream mitigation is required, the mitigation ratio shall be one to one (1:1) based on stream length for projects which propose stream channelization, hardening, or relocation. DWQ believes that this ratio is justified since the stream use would be degraded rather than removed. If the stream is to be culverted or otherwise buried, mitigation shall be at a 2:1 ratio since the aquatic life use will be lost in the channel1.Finally if the stream is classified as HWQ (ie., native and special native trout waters, primary nursery areas, WS-I, or WS-II) and SA waters),WS-III or ORW, then stream mitigation should be done on a stream within the same river subbasin when practical at twice the mitigation ratio as described earlier in this paragraph. In all cases, restoration should include restoration of both stream banks. 1 However since the operative DWQ policy with respect to stream mitigation ratios has been 1:1 since January 1997, this change to a 2:1 ratio for culverted streams will only be effective when this policy is finalized. DWQ welcomes comment on this provision. It y ? • Mitigation procedures for impacts to canals must be handled differently. Larger canals can have significant aquatic life especially in the outer coastal plain. However replacement of large canals in this landscape often requires wetland impacts. O DT,Q will only require mitigation for fill of those canals that the Corps of Engineers determine to be waters of the U.S. The 150 foot threshold still applies. Stream impact associated with construction of a pond for stormwater, irrigation or other purposes will not require mitigation for the stream impa= as long as the pond is designed to support aauatlc tife (i.e., with littoral shelves). However oond creation may not be used to mitigate for additional stream or wetland loss. Projects that propose to improve drainage through means such as channelization and dredging are not suitable sites for stream mitigation since the-aquatic !if-- in these systems is usually degraded or will be degraded by the stream work. Stream 1morOVement's which utlliZe bioengineering techniques which do not utilize cnnelizatior_, dredging or hard bottom structures are suitable candidates for stream mi-,_ ga-_ion efforts provide: thr t-:e streams are degraded. TI_. Mitigation techniques DWQ has developed a techniCal memorandum (see attachment) which addresses various technical aspects of stream mitigation. Mitigation should 1) be done on approximately the same size or order of stream, 2) replace or improve the physical characteristics of the stream to be i mmacted, 3) include rips _ ian measures such as planting of wooded buffers and livestock exclusion, S) be in the same river subbasin and 5) (where f? sible) be locate^ in watershe^s targeted in the basin:•:_de management plan to be partially or non-supporting their uses cue to nonpoint source problems. if suitable sites cannot be located or acquired, the search areas should be expanded to' adjacent subbasins. Legislation establishing the Wetland Restoration Program discusses mitigation for "wetlands and riparian areas". DWQ believes that this language allows an in-lieu payment to the program for stream mitigation by private and public parties on a dollar per linear foot basis. DWQ plans to establish a process with DOT whereby this procedure could be implemented rather than have DOT invest extensive staff resources for stream mitigation. Finally, the Environmental Management Commission on 10 April 1997 passed a temporary rule [15A NCAC 2R .0503 (b)(1)] to allow the Wetland Restoration Program to charge $125 per linear foot of stream in order to satisfy this mitigation need. This process should be an attractive option in many instances for the public and private sectors. IV. Cumulative Impact DWQ rules for permitting of stream fill also require consideration of cumulative impacts (15A NCAC 2H .0506 (b)(4)). This decision is especially important in linear or phased projects, Tn termns or streams, if any particular stream with positive 7Q10 or 30Q2 flow or with vertebrate aquatic life is planned to be impacted by fill (i.e., hardening or culverting) greater than 150 -feet, then mitigation will be required for the entire length including the 150 feet. Relocated streams which have these characteristics will be required to follow stream relocation guidelines. Past impacts which required 404/401 authorization wi11 be considered when adG'_tional impacts are planned in order to control cumulative impacts. Several possible scenarios are shot.-m- on the attached sketch for illustrative purposes and are discussed below. If multiple crossings of a particular stream are planned and the stream meets the flow/biotic criteria outlined above, then mitigation will be required if the total fill for that stream exceeds 1`50 feet. M? t_gation would be required for the enure amount of impact to the stream. Except as noted above, mitigation requirements will be considered separately for each stream. Tor instance if =111 for eacn separate strum (culverting) in a particular project is less than 150 feet, th-en stream mitigation wi 1 1 not be required for the prcDecc unless total fill of the stream exceeds 150 feet- due to multiple crossings of the same stream. I. a stream with positive 7Q10/30Q2 flow or vertebrate aau'atic life is straightened using bioena-sneering techniques, any loss of stream length. greater than 150 feet wi 1 1 require mitigation. I: bi oencri neeri na techniaues are not used-.. (for instance tine stream is placed in a concrete lined conveyance), then the entire 1 enath would re:i ire com-oensato?v mitigation if the lednath exceeds 150 feet. .gain, bridging of streams will not require compensa-torn mitication for the stream impacts since the aquatic life use is still present beneath the bridge. In addition, compensatory mitigation for wetland impacts may be reauired in accordance with 15A NCAC 2H .0506 (h). These procedures are outlined in separate DWQ policies. streamool.mem $FESIBLE STREAM COMPENSATORY MITIGATION SCENARIOS Division of Water Quality, Environmental Sciences Branch October 2. 1997 250 foot crossing - need 2:1 mitigation for entire 250 foot loss / / stream 150 foot crossing - no compensatory mitigation needed stream three 100 foot crossings (300 feet total) - compensatory mitigation at 21 rtio needed for 300 feet of impact since total stream crossings exceed 150 feet stream slope Relocated stream - if loss ((old stream (Lo) length minus new stream (Ln) length)) is greater than 150 feet, then compensatory mitigation at 1:1 ratio needed for difference as Iona as bioengineering techniques are used to relocate the stream.

WATER QUALITY SECTION March 31, 1998 MEMORANDUM.: TO: THROUGH: FROM John Dorney, Wetlands Group Wastewater- Consultant Forrest Westall, Supervisor Water Quality Section Roger Edwards`IF 5 SUBJECT:. Triple Creek S/D, Henderson County Project Number 98-0169 This subdivision does not culvert more than 150 feet of any one stream. The total footage of stream in culverts is in excess of 150 feet. While our regulations do not require mitigation for less than 150 feet of stream there are impacts to the environment when several hundred feet of stream is placed in culverts in the same drainage area. The opinion of the site inspector is the entrance culvert located in area six (6) could be changed to a bridge- The bridge may cost more than a culvert however, the bridge would enhance the entrance to the project. The bridge would prevent the lost of usefulness of that section of stream. The site visit confirmed that area three(3) is not a stream at the location of the culvert. The engineer is to evaluate the proposed road layout in area two(2). It is possible the road can be moved closer to the property line and prevent the installation of the culvert in the head of the stream. Areas 1, 4, and 5 are streams which will be placed in culverts. The park area should be a separate deed to the homeowners association or to a conservation group. This hopefully will prevent this wetland area from being destoried.

Based on this review, ,we have1dentified significant uses, which would be removed or degraded by this project. These uses are aquatic life uses in these streams. Furthermore, insufficient evidence is present in our files to conclude that your project must be built as planned in waters and/or wetlands in accordance with 15A NCAC 2H.0506. Therefore, unless modifications of the proposal are made as described below, we will have to move toward denial of your 401 Certification as required by 15A NCAC 2H .0507(e) and will place this project on hold as incomplete until we receive this additional information. Until we receive additional information, we are requesting (by copy of this letter) that the U.S. Army Corps of Engineers place your project on administrative hold. Please provide us with information supporting your position that states your project must be constructed as planned and that you have no practicable alternative to placing fill in these waters and/or wetlands. Specifically can you construct your road crossing at area #6 to a bridge and reconfigure the road alignment to avoid,-tream fill at #2? These alterations (especially those at area #6) would reduce the stream mitigation that would otherwise be required for this project. Any documentation such as maps and narrative that you can supply to address alternative designs for your project may be helpful in our review of your 401 Certification. Also this project will require compensatory mitigation as planned as described in 15A NCAC 2H .0506(h). Your mitigation proposal is insufficient because none is proposed. Please respond within two weeks of the date of this letter by sending a copy of this information to me and one copy to Mr. Roger Edwards, Asheville Regional Office at 59 Woodfm Place, Asheville NC 28801. If we do not hear from you in two weeks, we will assume that you no longer want to pursue this project and we will consider the project as withdrawn. I can be reached at 919-733-1786 if you have any questions.
