RE: NPDES Permit No. AR0044822 JAN 0 9 2013 Case No. CV 2010-32603 Higginson, Arkansas .... Dear Lindsay:

Enclosed you will find the following items concerning the referenced project .

1. One (1) set of Plans and Specifications 2. Corrective Action Plan 3. Design Calculations 4. Construction Permit Application (Form 1 and Form 2A) 5. Notice of Intent for Discharges of Stormwater for Large Site with SWPPP.

Please forward the enclosures to the proper person for review. At this point, we did not include a check for $200.00 for the large site storm water permit fee. We have proposed to apply the old sand from the sand filter beds to a six (6) acre adjacent grass site owned by the City. If we cannot do that, then we will. require the contractor to haul off and dispose of the old sand and the City will not need the large site storm water permit.

Very truly yours,

A. Site Description a. Project description, intended use after NO1 is filed: The proiect involves constructing improvements on an existing wastewater treatment plant site and on an open grass area adiacent to and on the east side of WWrP site. See site map. Part of the proiect involves rehabbing existing sand filters. It is proposed to applv the old sand removed from the sand filters to the 6 acre adiacent grass site, disk and mix the soil and then reestablish the grass cover on the site. It is proposed to install silt fence and small levee around perimeter of the 6 acre site as shown on site map with a silt fence barrier and small settlement basin and rock check dam to control runoff from site until grass is reestablished. The project also involves excavating on the WWTP site to install ~ipes, conduits, concrete boxes and manholes. Runoff from this part of the WWTP site will go to the 6 acre grass area site. All disturbed areas will have grass reestablished or be covered with gravel surface.

INSTRUCTIONS

Evaluate individual project sites for federally listed threatened or endangered species using the step process presented below.

STEP 1

Does your project occur within 660 feet of a bald eagle nest?

Yes See instructions below. No All other projects proceed to Step 2, unless your project occurs in the following counties then proceed to Step 9.

Cleveland Greene Lincoln Lonoke 11 Nevada

Projects occurring within 660 feet of a bald eagle nest, including alternate nests, are likely to disturb nesting bald eagles (a potential violation of the Bald and Golden Eagle Protection Act). Proceed to the U. S. Fish and Wildlife Service website (~://~w~.f~v~.~ov/~outhea~t/e~/baIdeagle)to determine if the new or intermittent activity is likely to disturb nesting bald eagles and measures that you can take to avoid that disturbance. Print three copies of the bald eagle signature (Determination) page and submit one with your ADEQ permit application package, submit one copy to the U.S. Fish and Wildlife Service at 110 South Amity Road Suite 300, Conway, AR, and keep one copy for your records.

Once the above is completed, projects occurring in Cleveland, Greene, Lincoln, Lonoke, or Nevada counties proceed directly to Step 10, all others proceed to Step 2.

If you answered "Yes" to Step 3, refer to the U. S. Fish and Wildlife Service Private Lands Guidelines (http://www.fws..gov/rcwrecovery/private lands .guidelines.pdf)for potentially harmful activities that may harass and/or harm red-cockaded woodpeckers (a violation of the Endangered Species Act). Checking "Yes" to Step 2 requires a concurrence letter from the U. S. Fish and Wildlife Service that should accompany your ADEQ permit application package and possibly a permit from the U. S. Fish and Wildlife Service (501-513-4481). Any and all other endangered species issues will be evaluated when your information is submitted to the U.S. Fish and Wildlife Service. Please contact the Arkansas ES Field Office, as soon as possible, to start the evaluation for endangered species that may be affected by the project.

Does your project occur within the delineated karst conservation zone (see map below)?

Yes See instructions below and then proceed to Step 4. No Proceed to Step 4.

If you answered "Yes" to Step 3, contact the US Fish and Wildlife Service (Service) Arkansas Field Off~ce(501-513-4470) in advance of permit application as a concurrence letter from the Service may be necessary as a part of your NPDESISWPPP application package. It may also require a Service section 10 endangered species permit. While the Service is interested in the proposed project due to its location, many areas within the karst conservation zone only require the standard recommendations below. Early contact with this ofice allows time to develop site specific recommendations which streamlines the permit issuance process. Any and all other endangered species issues will be evaluated when your information is submitted to the U.S. Fish and Wildlife Service.

The karst region in Arkansas is as an area with a relatively shallow soil profile where climatic events or storm water runoff quickly infiltrates and is transported through

4 U S FISH AND WILDLIFE SERVICE- ARKANSAS FIELD OFFICE 1I0 SOUTH AMITY ROAD, SUITE 300 I CONWAY, ARKANSAS 72032 PHONE 501 -5 13-4470 I FAX 501-5 13-4480 I \\gvw I\+_lg)~ I Rev~s~onDate 1012812010 underground passages contributing to the groundwater basin. The karst region in Arkansas supports 6 endangered species including the Ozark cavefish (Amblyopsis rosae), the Benton cave crayfish (Cambarus aculabrum), the Hell creek crayfish (Cambarus zophonastes), the gray bat (Myotis grisescens), the Indiana bat (Myotis sodalis), the Ozark big-eared bat (Corynorhinus townsendii ingens), and 19 globally imperiled karst dependent species.

If your project occurs inside the delineated karst conservation zone (map above) the Service recommends, at a minimum, the following conservation measures.

1) Survey for karst features including caves, springs, and sinkholes prior to initiating project activities. If such a feature is found, establish a 300 foot conservation zone around its location and contact the Service for an onsite karst evaluation.

2) If caves are excavated during construction activities, the Service requests that work efforts cease within 300 feet of the opening. The opening should be adequately marked, fill material should not be placed in the cave, personnel shouldn't enter the cave, and the Service should be contacted immediately for an onsite evaluation.

3) While sediment mobilization is the primary concern during construction; storm water runoff following project completion may contain oillgrease, sealants, tar, brake dust, herbicides, pesticides, and additional sediment. To reduce threats to surface and groundwater from these contaminants, the Service recommends the use of post construction storm water management techniques including detention basins or separation systems with a 100 foot bioswale. However, other post construction storm water management methods are available; these would be considered if documentation of successfUl use is provided to the Service prior to installation.

4) Apply and maintain construction BMP's that were developed specific for the project site.

Proceed to Step 4.

Does your project occur within 0.5 mile of the Arkansas River, White River, Mississippi River, or Red River?

Yes Follow instructions below. No Proceed to Step 6.

If you answered "Yes" and are willing to implement the recommendations below, a concurrence letter from the U. S. Fish and Wildlife Service is not necessary and you can proceed to Step 6. If you are unable to implement the guidelines below, a concurrence letter from the U. S. Fish and Wildlife Service should accompany your ADEQ permit application package. Implementing the following U. S. Fish and Wildlife Service guidelines to will prevent harassment and/or harm of Interior Least Tern populations.

1. The critical nesting period for the Interior Least Tern is between 15 May and 1 August. Nesting may extend beyond these dates depending on river stage elevations. If surveys reveal Interior Least Tern breeding activities within 0.5 mile of a proposed activity during this time period, no activity should proceed unless otherwise approved by the U. S. Fish and Wildlife Service (501 -5 13-4470).

2. No activities should take place closer than 1,000 feet of the shoreline of a nesting colony location. The U. S. Fish and Wildlife Service should be contacted for further consultation if activities are to proceed within 1,000 feet of the shoreline of a nesting colony location. Limited construction outside of the active nesting season may not affect Interior Least Tern. Detailed project description, designs, and construction date information is necessary for U. S. Fish and Wildlife Service concurrence.

3. Employees and/or contractors should be instructed that under no circumstances (other than emergencies) are they permitted on a nesting island during the aforementioned time period and until after the young have fledged.

Please include site photographs or other supporting information to help the Service further evaluate whether these characteristics are present. In general, but not limited to, any one of the following project characteristics exclude the need to conduct an American Burying Beetle survey:

Projects with less than three acres of soil disturbance. Soil that is greater than 70 percent sand. Soil that is greater than 70 percent clay. Land where greater than 80 percent of the soil surface is comprised of rock. Land where greater than 80 percent of the subsurface soil structure within the top four inches is comprised of rock. Land that has already been developed and no longer exhibits topsoil or leaf litter. Land that is tilled on at least an annual basis. Land that meets the U.S. Army Corps of Engineers definition of wetland. Pine plantations planned for mechanical treatment where stocking density is 750 or more trees per acre (little sunlight to forest floor). Shortleaf pine or mixed pine-hardwood forest stands with 110 square feet per acre or greater overstory basal area and more than 700 stems per acre occupying midstory and understory positions. Land that is bordered by dense urban development (when in doubt request Service concurrence). Dense cedar thickets.

The Service evaluates numerous other project characteristics such as type, duration, permanency, land use, location, timelseason, and habitat to determine if a survey is required. If you have questions regarding the need for a survey, please contact the U. S. Fish and Wildlife Service at 50 1-5 13-4470. American Burying Beetle surveys can only be conducted between May 20 and September 20 and are valid for one year. Please plan ahead. If you answered "Yes" to Step 7, a concurrence letter from the U.

Does your project occur in Ashley, Bradley, Clay, Drew, Izard, Jackson, Lawrence, Washington, or Woodruff counties AND are one or more of the following federally listed plants present (Virginia Sneezeweed, Missouri Bladderpod, Pondberry, Running Buffalo Clover, and/or Geocarpon minimum). Should one of these plants be discovered on the property during project implementation, see instructions below and contact U. S. Fish and Wildlife Service for additional technical assistance to avoid violating the prohibitions of section 9 of the Endangered Species Act.

1. Avoid use of pre-emergent herbicides in areas with federally listed species and state species of concern.

2. Avoid herbicide use at any known site inhabited by federally listed plants during the following time periods:

a. Virginia Sneezeweed (Helenium virginicum): Spring "green up" until first frost.

b. Geocurpon minimum: February through June.

c. Missouri B ladderpod (Physaria (Lesquerella)Jiliformis): July through September

d. Pondberry (Lindera melissifolia): Bud inhibitor agents could damage plants during December through February. Plants flower in early spring before leaves are active, avoid herbicide applications fiom flowering through February.

e. Running Buffalo Clover (Trifolium stoloniferum): August through February.

f. Harparella (Ptilimnium nodosum): May through October. Since this species occurs in stream channels and is typically underwater during this time, we assume it is dormant. It begins growing as stream waters recede in the spring and flowers and fruits in the summer when water in the stream channel is low.

3. Maintain native glade and sinkhole pond vegetation by minimizing or avoiding activities in this habitat type.

4. Pondberry is a wetland plant that is often found in sand pond habitats in eastern Arkansas, low sandy ridges in hardwood bottoms in the St. Francis Sunken Lands, and in the Ouachita River bottoms. BMPs directed toward minimizing runoff and erosion or introduction of contaminants into these areas should be employed.

If you answered "Yes" to Step 8 AND cannot implement the four recommendations listed above OR the project will have direct impacts on federally listed plants, contact the U. S. Fish and Wildlife Service for conservation recommendations prior to project implementation. Any and all other endangered species issues will be evaluated when your information is submitted to the US.

Dear Mr. Holcomb:

The U.S. Fish and Wildlife Service (Service) has reviewed the information supplied in your letter dated August 20, 2010, regarding the proposed sewage system improvements in Higginson, White County, Arkansas. Our comments are submitted in accordance with the Endangered Species Act (87 Stat. 884, as amended 16 U.S.C. 1531 et seq.).

The submitted project is located in the White River watershed. The endangered pink mucket (Lampsilis abrupta), scaleshell (Leptodea leptodon), and fat pocketbook (Potarnilus capax) are known to occur in the White River. To prevent these projects from adversely affecting these endangered species, the Service recommends that best management practices (BMPs) should be properly installed and maintained throughout construction. These BMPs should be maintained until the site is adequately re-vegetated to prevent soil loss and sedimentation in nearby streams.

We appreciate your interest in the conservation of endangered species. If you have any questions, please contact Chris Davidson at (501) 513-4481 or Sarah Pavan at (501) 513-4487.

Sincerely, A a

f SOIL MAP AND DESCRIPTIONS

The majority of the soil that exists on the proposed construction site consists of the Loring silt loam. The Loring silt loam consists of soils that are flat or nearly level which are moderately well drained with a slight erosion hazard. Permeability is moderately slow. Typically, the surface layer is brown sClt about 7 inches thick. The subsoil extends to a depth of about 72 inches. To a depth of 14 inches, it is strong brown friable silt loam, and to a depth of 26 inches, it is yellowish brown silty clay loam. Below that it is a firm, brittle fragipan. The upper 13 inches of the fragipan is yellowish brown, mottled silt loam and the lower part is yellowish brown, mottled silty clay loam.

A copy of the White County, USDA soil descriptions for this soil type is included here.

The existing storm water drainage is from a thick turfed grass area that likely results in good quality water runoff except during a heavy flash storm event.
