WASTE DISCHARGE REQUIREMENTS

FOR

TARTARIC MANUFACTURING CORPORATION, INC.

PLANT #2

CLASS II SURFACE IMPOUNDMENTS

NEWMAN PLANT

STANISLAUS COUNTY

 

1. Tartaric Manufacturing Corporation, Inc. (hereafter Discharger) owns and operates Tartaric Plant #2 Class II Surface Impoundments. The facility was previously regulated by Waste Discharge Requirements (WDRs) Order No. 97-196 in conformance with Title 27 California Code of Regulations (CCR) Division 2 Subdivision 1 (hereafter Title 27). The Discharger submitted a Report of Waste Discharge on 2 July 1998 requesting construction of two additional Class II surface impoundments and one settling basin, and approval of an engineered alternative to the prescriptive requirements of surface impoundment liners.
2. The facility is at 2155 Hills Ferry Road in Newman, California. This property is described by Assessor's Parcel Number 49-40-04 in Section 16, T7S, R9E, MDB&M. The elevation of the site is 70 feet above mean sea level, and is on the western side of the San Joaquin Valley as shown on Attachment A, which is incorporated herein and made a part of this order.
3. The facility consists of five Class II surface impoundments as shown on Attachment B which is incorporated herein and made a part of this Order. Ponds 1, 2, and 3, have been constructed and the discharger proposes to construct two additional Class II surface impoundments, ponds 4 and 5, and a solid removal basin that includes two concrete compartments.
4. About 100,000 gallons per day (gpd) of process wastewater are discharged to the surface impoundments from August to March resulting in 21 million gallons per year of wastewater.

 

WASTES AND THEIR CLASSIFICATION

5. The discharge, especially after evaporative concentration, poses a significant threat to water quality. Therefore, the discharge is a ‘designated waste' and as such must be discharged to a Class II surface impoundment as required by Title 27.
6. The Report of Waste Discharge described the waste as containing water, potassium sulfate, small amount of lees (semi-solid by-product from making wines) and small amount of calcium hydroxide.

 

DESCRIPTION OF THE SITE

7. The beneficial uses of the ground water beneath the site are: industrial, municipal, domestic and agricultural supply. There are 16 wells within 5,000 feet of the site. Water from these wells is used for domestic, agricultural and industrial supply.
8. Surface water drainage from the site generally trends eastward and is tributary to the San Joaquin River. Unnamed, dry creek beds and the Newman Wastewater Channel lie between the site and the San Joaquin River (approximately 3 miles east of the site).
9. The facility receives less than 10 inches of precipitation per year. The mean evaporation rate is greater than 47 inches per year.
10. The topography of the site is on the flat lying plain in the Central Valley basin. Geologically, the site lies within the western boundary of Great Valley geomorphic province. The uppermost stratigraphic sequence of this province consists of coalescing low alluvial fans and river flood plain deposits.
11. The nearest active Holocene fault is the Ortigalita Fault, which is 5.6 miles away. The threat of ground rupture at the site is highly unlikely.
12. The 24-hour, 1,000 year storm event at the Los Banos station, approximately 21 miles south of the plant, is 3.21 inches.
13. There are at least three occurrences of groundwater beneath the site: (1) the unconfined aquifer, (2) the confined aquifer, and (3) the water within consolidated rocks.
14. The unconfined aquifer occurs in unconsolidated deposits above the Corcoran Clay and has moderate to large water yielding Holocene to Pleistocene sediments. This unconfined aquifer is the most extensively developed aquifer in the Modesto-Merced area, yielding water to domestic, irrigation, industrial, and public-supply wells. Well yields are as large as 4,500 gallons per minute (gpm), with a median of approximately 2,000 gpm. In the area of the site, wells commonly yield 1,500 gpm. Groundwater movement is eastward and southeastward towards the San Joaquin River
15. The confined aquifer occurs in the unconsolidated deposits below the Corcoran Clay. The bottom of the confined aquifer is likely at the top of the Miocene-Pliocene Mehrten Formation (approximately 800 - 1000 feet below ground surface). Wells perforated in the confined aquifer below the confining Corcoran Clay (approximately 140 to 190 feet below ground surface) have similar yields as the unconfined aquifer. Groundwater movement is likely to east and southeast towards the valley trough. Water quality is not well known within the confined aquifer.
16. Lastly, the water within consolidated rocks is likely confined. Little is known about the water-bearing zones within the consolidated rocks. Likewise, the movement of groundwater and water quality is also unknown in this hydrologic unit.
17. The Discharger has constructed four monitoring wells with depth to groundwater from land surface ranging from 8 to 10 feet. Based on one sampling event in March 1998, water quality for these wells ranged from: chloride, 149-392 mg/l; sulfate, 95-167 mg/l; TDS, 947-1805 mg/l; electric conductivity, 1480-2820 m mhos/cm.

 

DESCRIPTION OF SETTLING BASIN

18. The Discharger proposes to settle out the settleable solids from the process water in a concrete basin prior to entering a filter press and then the Class II surface impoundments. The wastewater contains suspended and dissolved solids from lees processing to produce calcium tartrate. The settling basin will be northeast and adjacent to the existing Pond 1.
19. The basin will consist of two parallel compartments each with a capacity of about 25,000 gallons and will have a decant line into the diatomaceous earth filter press. Effluent from the filter press will be piped to the evaporation ponds.
20. The design will consist of a 40 mil thick PVC liner followed by a layer of 6 oz/yd² thick non-woven geotextile. A 4 to 6 in thick layer of 3/4 inch diameter round drain rock will be placed above the geotextile layer. A layer of concrete will be installed above the drain rock. A leachate collection and recovery system (LCRS) equivalent to the LCRS under the current Class II surface impoundments will be constructed.

 

DESCRIPTION OF CLASS II SURFACE IMPOUNDMENTS

21. The capacity of pond 1 is 2.5 acre-feet and ponds 2 and 3 are 25.0 acre-feet each. These ponds are lined with an engineered alternative to the prescriptive liner requirements defined under Title 27. The surface impoundments were constructed with an outer layer of 40-mil HDPE synthetic liner, a geonet leachate collection system, and a 40-mil HDPE synthetic inner liner. The leachate collection and recovery system (LCRS) drains to a sump where leachate is pumped back to the surface impoundment.
22. Each pond has a "pan type" lysimeter leachate detection system placed one foot below the synthetic liner system sump, which discharges drainage to the LCRS manholes. These lysimeters are constructed with a geonet and 40-mil synthetic liner below the surface impoundment bottom liner.
23. The Discharger proposes an alternative to the prescriptive liner requirements for the lower component of the liner system for the new Class II surface impoundments. The alternative design for ponds 4 and 5 will be the same as the existing ponds with an outer layer of 40-mil HDPE synthetic liner, a geonet leachate collection system, and a 40-mil HDPE synthetic inner liner. The new Class II surface impoundments will also have "pan type" lysimeters leachate detection system as described in Finding 22. Both of these Class II surface impoundments will have a capacity of 40 acre feet.

 

ENGINEERED ALTERNATIVE

24. The Discharger's RWD dated 5 September 1997 proposed an alternative to the prescriptive liner requirements for the lower component of the liner systems for the Class II Surface Impoundments. The discharger stated that the liner systems meet the requirements of an engineered alternative under Section 20080 of Title 27 to provide equivalent water quality protection to the prescriptive liner standard. The engineered alternative was approved by the Board in Order No. 97-196, adopted 19 September 1997.

 

CEQA AND OTHER CONSIDERATIONS

25. The action to revise WDRs for this facility is exempt from the provisions of the California Environmental Quality Act, (Public Resources Code, Section 21000, et seq.), in accordance with Title 14, CCR, Section 15301.
26. This Order implements
1. the Water Quality Control Plan for the Sacramento River and San Joaquin River Basin, Third Edition;
2. the prescriptive standards and performance goals of Title 27 of the California Code of Regulations (CCR), effective 18 July 1997, and subsequent revisions.

E. WATER QUALITY PROTECTION STANDARDS

The Water Quality Protection Standard (Standard) shall consist of the following elements:

1. Constituents of Concern 4. Points of Compliance

2. Concentration Limits 5. Compliance Period

3. Monitoring Points

Each of these is described as follows:

1. Constituents of Concern

The ‘COC list' (list of Constituents of Concern required under 27 CCR 20395) shall include all constituents listed in Tables 1 and 2 and in Waste Discharge Requirements Order No. 98-183. The Dischargers shall monitor all COCs every five years, or more frequently as required under the corrective action monitoring program

2. Concentration Limits

The Discharger shall determine the Concentration Limit for any given Constituent of Concern or Monitoring Parameter in a given monitored medium(i.e., groundwater and surface water) at the landfill shall be as follows, and shall be used as the basis of comparison with data from the Monitoring Points in that monitored medium:

a. The mean (or median, as appropriate) and standard deviation (or other measure of central tendency, as appropriate) of the constituent's background data; or

b. The constituent's background value, established anew during each Reporting Period using only data from all samples collected during that Reporting Period from the Background Monitoring Points for that monitored medium. Either:

1) The mean (or median, as appropriate) and standard deviation (or other measure of central tendency, as appropriate) of the constituent's background data; or

2) The constituent's MDL, in cases where less than 10 percent of the background samples exceed the constituent's MDL; or

c. A concentration limit greater than background, as approved by the Board for use during or after corrective action.

3. Monitoring Points

The groundwater monitoring points for detection and evaluation monitoring shall be background monitoring wells MW-1 and MW-5, and downgradient wells MW-2, MW-3, MW-4, MW-6, and MW-7. The surface water monitoring points for detection monitoring shall be S-1. The unsaturated monitoring point for the detection monitoring shall be collected from the lysimeters, LS-1, LS-2 and LS-3, LS-4, and LS-5 beneath the compositely lined portion of surface impoundment unit.

4. Points of Compliance

The points of compliance for groundwater are monitoring wells MW-2, MW-3, MW-4, MW-6, and MW-7. The points of compliance for surface water are monitoring stations S-1. The points of compliance for unsaturated zone are LS-1, LS-2, LS-3, LS-4, and LS-5..

5. Compliance Period

The Compliance period is the number of years equal to the active life of the surface impoundments plus the closure period. Each time the Water Quality Protection Standard is exceeded (i.e., a release is discovered), the surface impoundment begins a Compliance Period on the date the Board directs the Dischargers to begin an Evaluation Monitoring Program. If the Discharger's Corrective Action Program (CAP) has not achieved compliance with the Standard by the scheduled end of the Compliance Period, the Compliance Period is automatically extended until the surface impoundment or landfill has been in continuous compliance for at least three consecutive years.

The Dischargers shall implement the above monitoring program on the effective date of this Order.

TARTARIC MANUFACTURING CORPORATION, INC.

PLANT #2

CLASS II SURFACE IMPOUNDMENTS

NEWMAN PLANT

STANISLAUS COUNTY

 

 

Tartaric Manufacturing Corporation, Inc. constructed three Class II surface impoundments, Ponds 1, 2, and 3, for the processing of calcium tartrate. The plant collects "lees", a semi-solid paste (10 to 20% humidity), remaining from the production of wine, for the purpose of leaching out calcium tartrate. The facility is in the City of Newman at an elevation of 70 feet above mean sea level. Tartaric is planning to construct a solid removal system that includes two 25,000 cubic feet concrete settling basins and two additional Class II surface impoundments, Ponds 4 and 5.

 

The process water, containing primarily potassium sulfate, small amount of lees, calcium hydroxide and water, will first flow to the solids removal system for solids settling. The water will then flow to the Class II surface impoundments for evaporation. The pH will be between 6 and 9. The wastes are classified as designated under Title 27.

 

Pan-lysimeters will be placed underneath all five Class II surface impoundments and will act as leachate collection system. All Class II surface impoundments and the solids removal system have leachate collection and recovery system (LCRS).

 

The climate at the site is such that evaporation is over 47 inches per year, while rainfall is less than 10 inches per year.

 

Groundwater beneath the site occurs in three zones. These are (1) the unconfined aquifer from 10 to approximately 140 feet below ground surface; (2) the confined aquifer from approximately 140 to 800 feet below ground surface, ad (3) the water within consolidated rocks 800 feet below ground surface. The strata in the unconfined aquifer consists mostly of sand, silty clay, sandy silt and clayey/sandy silt, with some gravels. The strata in the confined aquifer is similar and lies below a massive clay zone known as the Corcoran Clay. Little information is known about the consolidated rocks zone. Monitoring wells will be installed in unconfined aquifer for detection monitoring purposes.

 

Surface water drainage is to an unnamed dry stream which flows east into San Joaquin River.
