1 Waste Management Plan - Land Application of Water Treatment Residuals

1.0 INTRODUCTION

This management plan is submitted by the Denali Water Solutions (DENALI) on behalf of the Arkansas Department of Corrections - Tucker Unit (TUCKER) to the Arkansas Department of Environmental Quality (ADEQ) along with a completed Notice of Intent for a new General Permit 0000-WG-WR for the land application of water treatment residuals generated at the TUCKER Water Treatment Facility. These materials will be land applied for beneficial use on TUCKER property in Jefferson County. This waste management plan addresses the land application of residuals generated during the treatment of drinking water.

2.0 WASTE CHARACTERISTICS

Water Treatment Residuals: The residuals that accumulate in the holding ponds at potable water treatment facilities consist of water filter backwash residues. This material is non-hazardous and contains low levels of plant available nutrients. Because lime or alum is often used in the water treatment process, significant amounts of these materials can be found in the residuals.

Typical analytical results for water treatment residuals are presented in Appendix A

3.0 WATER TREATMENT RESIDUALS PRODUCTION

Water treatment residuals production typically varies a water treatment facilities depending on several factors including: raw water quality based primarily on the Total Suspended Solids (TSS) content, the volume of chemicals used, and the seasonal water usage/demand. The TUCKER WTP utilizes sodium carbonate (soda ash) to treat the approximately 500,000 gallons of raw water per day with an average estimated Total Suspended Solids (TSS) content of 12 mg/l. The Booneville WTP produces approximately 10.125 dry tons/year based on the following calculations:

Average Raw Water TSS – 12 mg/l Annual sodium carbonate – 2,000 lbs (12 mg/l x 500,000 gal/day x 8.34 lb/gal) / 1,000,000 = 50 lb/day 50 lb/day x 365 days/yr = 18,250 lb/year Estimated Annual Dry Residuals Produced = 18,250 + 2,000 = 20,250 lb/year = 10.125 tons/year

2 Waste Management Plan - Land Application of Water Treatment Residuals

4.0 DESCRIPTION OF WATER TREATMENT RESIDUALS STORAGE FACILITIES

The TUCKER Water Treatment Plant utilizes a 36,000 ft3 earthen backwash pond for storage of water treatment residuals. DENALI has been contracted to remove the accumulated water treatment residuals from the backwash pond. It is estimated that 270,000 gallons of water treatment residuals must be removed to restore the approximate design storage capacity of the backwash pond.

Aerial topographic maps showing the storage components and overall location of the treatment facility and with residuals storage components are presented in Appendix E.

5.0 LAND APPLICATION

Liquid water treatment residuals will be thoroughly mixed prior to removal from the holding cell with the use of a lagoon pump equipped with an agitator. Residuals will be transported to the land application sites via sealed tanker trucks. In most cases, the material will be land applied via surface spreading. It may be spread directly from the tank trucks which will be equipped with splat plates, or from spreader buggies.

TUCKER will adhere to the following management practices.

1. Residuals will be applied evenly at rates not to exceed the 10 dry ton/acre/year limit imposed by the permit.

2. Buffer zones will be maintained as required by the permit.

3. Residuals will not be land applied to gradients greater than 15%; or to soils that are saturated, frozen or covered with snow, during rain or when precipitation is imminent, meaning a substantial natural occurrence of precipitation that could cause significant damage to property or threaten human life in the near future.

6.0 LOADING RATES

Representative samples of the residuals to be land applied will be analyzed and the results will be expressed in dry basis in mg/kg, unless specified by the permit.

Application rates expressed in either dry ton per acre (dt/ac) or gallons per acre (gal/ac) will be such that the 10 dt/ac limit as specified in the General Permit will not be exceeded on an annual basis. Pollutant loading rates expressed in pounds per acre (lb/ac) for each of the parameters listed in the following Pollutant Limits table will be calculated annually as follows: 3 Waste Management Plan - Land Application of Water Treatment Residuals

Should any one of the Cumulative Pollutant Loading Rate limits listed in the table below be reached on a given field, land application shall cease for the remaining term of the permit. Residuals analyses that indicate an exceedance of any one of the Ceiling Concentrations limits listed in the following table will not be land applied.

7.0 LAND APPLICATION SITES

With this application, the TUCKER proposes to permit 18 acres for this project on facility property in Jefferson County. Land application site information which includes the acreage available, section, township, range, latitude, longitude, and nearest stream is presented in Appendix B. Soil survey maps and soil descriptions are presented in Appendix C.

8.0 RECORD KEEPING AND REPORTING

Land application logs will be maintained that include the field name or number, applicator’s name, application date and time, volume, and application rate. Annually, DENALI will provide to ADEQ a report which includes the information on the field logs, laboratory analyses of the land applied water treatment residuals, metals loading rates, and soil analyses.
