RE: Sholi Term Activity Authorization-Great Lakes Chemical Company Brine Pipeline Section SWD 9S to SWD 21 S Replacement in Union County, AR

Dear Mr. Ingram:

The Arkansas Depaliment of Environmental Quality ("ADEQ") has completed its review the above referenced request for a short term activity authorization for Great Lakes Chemical Company to facilitate the replacement ofbrine pipeline known as the SWD 9S to SWD 21S. Three unnamed tributaries of Little Cornie Bayou will be trenched for brine pipeline replacement. After the pipeline replacement areas disturbed will be returned to pre-construction contours. BMP' s will be utilized in accordance to the sites SWPPP to prevent erosion and control sedimentation to the practicable extent. The project stream crossings are located in Section 31, T 18 S, R 15 W, approximately 7 miles south ofEl Dorado just off South Field Cutoff in Union County, Arkansas (Lat: 33.10609, Long: -92.69778).

The applicant is responsible for compliance with all applicable terms and conditions of this authorization. Receipt of this authorization does not relieve any applicant of the responsibility to comply with any other applicable federal, state or local statute, ordinance, policy, or regulation.

ADEQ hereby grants you a one time short term activity authorization for the stream crossing activities involved in the completion of the repair project, subject to the following conditions:

1. The applicant will limit the construction activity to low flow conditions as much as possible. The applicant will take all reasonable measures to limit equipment and machine usage in the wetted areas of the streams. This authorization does not include channel alteration.

2. The applicant will utilize best management practices to minimize the impacts of sedimentation and turbidity in each stream. The applicant's activities shall not cause violations of any other water quality standards.

3. The contractor shall document the date and duration of each water body crossing and the specific BMPs utilized to minimize impacts to the water quality of the water body. This information shall be kept for a period of 6 months after completion of the water body crossing and this information shall be made available to the Director upon request.

4. A short term activity authorization has been issued pursuant to the Arkansas Pollution Control and Ecology Commission's Regulation No.2, Section 2.305(F). This authorization is for a period of one (1) week per crossing, beginning upon the initiation of in stream activities. Ifthe projects are not completed within the one week per crossing time period, the applicant should contact ADEQ to request a new STAA.

5. The applicant will take all reasonable measures to prevent the spillage or leakage of any chemicals, oil, grease, gasoline, diesel, or other fuels. In the unlikely event such spillage or leakage occurs, the applicant will notify ADEQ immediately.

6. No construction activity is authorized in any stream designated as Extraordinary Resource Waters, Natural and Scenic Waterways, or Ecologically Sensitive Water bodies without prior water quality certification.

7. The applicant shall cease construction activity immediately ifthe ADEQ Director rescinds or revokes this short term activity authorization in writing.

8. If the construction site will disturb in excess of one (1) acre, the applicant must comply with the terms of the Stormwater Construction General Permit Number ARR 150000 prior to the start of construction. Best Management Practices (BMPs) must be implemented regardless of the size. More information can be obtained by contacting the NPDES Storm water Section of ADEQ at (50 1) 682-0621 .

9. The applicant shall comply with all aspects of the existing MS4 permit (ARS000002).

10. This short term activity authorization has been issued to allow for the temporary exceedance of the turbidity standard only.

In issuing this authorization, ADEQ does not assume any liability for the following: A. Damages to the proposed project, or uses thereof, as a result of other permitted or

unpermitted activiti·es or from natural causes. B. Damages to persons, property, or to other permitted or unpermitted activities or

structures caused by this authorization. C. Design or construction deficiencies associated with this proposed project.

If you have any questions, please contact Mr. Mark Hathcote ofthe Water Division at (501) 682-0028.

PrefaceSoil surveys contain information that affects land use planning in survey areas. Theyhighlight soil limitations that affect various land uses and provide information aboutthe properties of the soils in the survey areas. Soil surveys are designed for manydifferent users, including farmers, ranchers, foresters, agronomists, urban planners,community officials, engineers, developers, builders, and home buyers. Also,conservationists, teachers, students, and specialists in recreation, waste disposal,and pollution control can use the surveys to help them understand, protect, or enhancethe environment.

Various land use regulations of Federal, State, and local governments may imposespecial restrictions on land use or land treatment. Soil surveys identify soil propertiesthat are used in making various land use or land treatment decisions. The informationis intended to help the land users identify and reduce the effects of soil limitations onvarious land uses. The landowner or user is responsible for identifying and complyingwith existing laws and regulations.

Although soil survey information can be used for general farm, local, and wider areaplanning, onsite investigation is needed to supplement this information in some cases.Examples include soil quality assessments (http://www.nrcs.usda.gov/wps/portal/nrcs/main/soils/health/) and certain conservation and engineering applications. Formore detailed information, contact your local USDA Service Center (http://offices.sc.egov.usda.gov/locator/app?agency=nrcs) or your NRCS State SoilScientist (http://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/contactus/?cid=nrcs142p2_053951).

Great differences in soil properties can occur within short distances. Some soils areseasonally wet or subject to flooding. Some are too unstable to be used as afoundation for buildings or roads. Clayey or wet soils are poorly suited to use as septictank absorption fields. A high water table makes a soil poorly suited to basements orunderground installations.

The National Cooperative Soil Survey is a joint effort of the United States Departmentof Agriculture and other Federal agencies, State agencies including the AgriculturalExperiment Stations, and local agencies. The Natural Resources ConservationService (NRCS) has leadership for the Federal part of the National Cooperative SoilSurvey.

Information about soils is updated periodically. Updated information is availablethrough the NRCS Web Soil Survey, the site for official soil survey information.

Map Unit DescriptionsThe map units delineated on the detailed soil maps in a soil survey represent the soilsor miscellaneous areas in the survey area. The map unit descriptions, along with themaps, can be used to determine the composition and properties of a unit.

A map unit delineation on a soil map represents an area dominated by one or moremajor kinds of soil or miscellaneous areas. A map unit is identified and namedaccording to the taxonomic classification of the dominant soils. Within a taxonomicclass there are precisely defined limits for the properties of the soils. On the landscape,however, the soils are natural phenomena, and they have the characteristic variabilityof all natural phenomena. Thus, the range of some observed properties may extendbeyond the limits defined for a taxonomic class. Areas of soils of a single taxonomicclass rarely, if ever, can be mapped without including areas of other taxonomicclasses. Consequently, every map unit is made up of the soils or miscellaneous areasfor which it is named and some minor components that belong to taxonomic classesother than those of the major soils.

Most minor soils have properties similar to those of the dominant soil or soils in themap unit, and thus they do not affect use and management. These are callednoncontrasting, or similar, components. They may or may not be mentioned in aparticular map unit description. Other minor components, however, have propertiesand behavioral characteristics divergent enough to affect use or to require differentmanagement. These are called contrasting, or dissimilar, components. They generallyare in small areas and could not be mapped separately because of the scale used.Some small areas of strongly contrasting soils or miscellaneous areas are identifiedby a special symbol on the maps. If included in the database for a given area, thecontrasting minor components are identified in the map unit descriptions along withsome characteristics of each. A few areas of minor components may not have been


8

observed, and consequently they are not mentioned in the descriptions, especiallywhere the pattern was so complex that it was impractical to make enough observationsto identify all the soils and miscellaneous areas on the landscape.

The presence of minor components in a map unit in no way diminishes the usefulnessor accuracy of the data. The objective of mapping is not to delineate pure taxonomicclasses but rather to separate the landscape into landforms or landform segments thathave similar use and management requirements. The delineation of such segmentson the map provides sufficient information for the development of resource plans. Ifintensive use of small areas is planned, however, onsite investigation is needed todefine and locate the soils and miscellaneous areas.

An identifying symbol precedes the map unit name in the map unit descriptions. Eachdescription includes general facts about the unit and gives important soil propertiesand qualities.

Soils that have profiles that are almost alike make up a soil series. Except fordifferences in texture of the surface layer, all the soils of a series have major horizonsthat are similar in composition, thickness, and arrangement.

Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity,degree of erosion, and other characteristics that affect their use. On the basis of suchdifferences, a soil series is divided into soil phases. Most of the areas shown on thedetailed soil maps are phases of soil series. The name of a soil phase commonlyindicates a feature that affects use or management. For example, Alpha silt loam, 0to 2 percent slopes, is a phase of the Alpha series.

Some map units are made up of two or more major soils or miscellaneous areas.These map units are complexes, associations, or undifferentiated groups.

A complex consists of two or more soils or miscellaneous areas in such an intricatepattern or in such small areas that they cannot be shown separately on the maps. Thepattern and proportion of the soils or miscellaneous areas are somewhat similar in allareas. Alpha-Beta complex, 0 to 6 percent slopes, is an example.

An association is made up of two or more geographically associated soils ormiscellaneous areas that are shown as one unit on the maps. Because of present oranticipated uses of the map units in the survey area, it was not considered practicalor necessary to map the soils or miscellaneous areas separately. The pattern andrelative proportion of the soils or miscellaneous areas are somewhat similar. Alpha-Beta association, 0 to 2 percent slopes, is an example.

An undifferentiated group is made up of two or more soils or miscellaneous areas thatcould be mapped individually but are mapped as one unit because similarinterpretations can be made for use and management. The pattern and proportion ofthe soils or miscellaneous areas in a mapped area are not uniform. An area can bemade up of only one of the major soils or miscellaneous areas, or it can be made upof all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example.

Some surveys include miscellaneous areas. Such areas have little or no soil materialand support little or no vegetation. Rock outcrop is an example.

Mr. Jamal Solaimanian Arkansas Department of Environmental Quality Discharge Permits Section 5301 Northshore Drive North Little Rock, AR 72118-5317

RE: NPDES Permit Tracking No. ARR153261 Brine Pipeline Replacement Additional Acreage Request

Dear Mr. Solaimanian:

Great Lzfws Chemic-al Corp.

Great Lakes Chemical Corporation (GLCC) in El Dorado, Arkansas wishes to request an amendment to the authorization to discharge associated with the above referenced permit tracking number. The amendment reflects an increase in the total estimated disturbed area due to construction activities. An additional 8.0 acres is considered for the total amount disturbed and for the total project area. The additional disturbance will include the replacement of two sections of brine pipeline along an existing pipeline right-of-way (ROW). Impacts for this project will be confined to temporary disturbance of herbaceous vegetation in the maintained ROW.

The pipeline sections being replaced are referred to as SWD 9S to South Plant and SWD 21 S to Header. Both sections of the brine pipeline are located approximately two miles south of the intersection of Parkers Chapel Road and South Field Road. SWD 98 to South Plant runs in a general wesUeast direction for approximately 1. 78 miles and the SWD 21 S to Header runs in a north/south direction for approximately 0.33 miles.

Attached are maps showing the current ARR153261 permitted area and the proposed additional disturbed areas, soil data for the project areas, as well as the additional measures anticipated to control erosion and sedimentation. In addition, a Short Term Activity Authorization has been requested for in-stream activities associated with the pipeline replacement.

If you have any questions regarding this revision, please contact me at 870-864-1557 or Josh Fluger with GBMc & Associates at 501-847-7077.

Sincerely, Great Lakes Chemical Corporation
