3 Wastewater Monitoring Data This language applies for data included for the Joint Water Pollution Control Plant (JWPCP) and the Long Beach, Los Coyotes, Pomona, San Jose Creek, Saugus, Valencia, and Whittier Narrows Water Reclamation Plants (WRPs). 1. ORGANIZATION OF THE DATA Flow and laboratory data sets are presented in separate tables, and statistical summaries follow the data. These data summaries may contain results that were not reported in monthly monitoring reports. Additional data can result from sampling conducted for purposes other than routine monitoring. The additional sampling may have been performed by other agencies (i.e., Regional Board or USEPA) or by the Sanitation Districts for research or as a follow-up to a questionable sample. 2. DETECTION LIMITS Information in the annual report regarding detection limits is consistent with reporting requirements in the effective permits for the treatment plants. The Method Detection Level (MDL) and Minimum Level (ML)/Reporting Level (RL) for each constituent may have varied throughout the year. These are included directly in the tabular data as a range over the calendar year. Sample results are reported in accordance with the methodology listed below. 1. Sample results greater than or equal to the RL are reported as measured by the laboratory (i.e., the measured chemical concentration of the sample). 2. Sample results less than the RL, but greater than or equal to the laboratory s MDL, are reported as Detected, but Not Quantified, or DNQ. The estimated chemical concentration of the sample is shown as DNQ, Est. Conc.=. 3. Sample results less than the laboratory s MDL are reported as Not Detected, or ND. 3. DATA CALCULATIONS Calculations of Sums A few parameters, such as DDT and PCBs, are reported as sums. In those cases, the total detected DDT and total detected PCBs are shown. Results that are below the RL are not included in the sum. Consequently, if none of the isomers/congeners was detected, the total is reported as ND. Calculations of Averages The following conventions are used in the annual report for data when more than one result is available and an average is determined: Monthly Averages If the data are all detected, an arithmetic average is calculated. When one or more sample results contain one or more reported determinations of DNQ or ND, a median is used in place of the arithmetic mean in accordance with the following procedure: 1

4 Wastewater Monitoring Data 1. The sample results are ranked from low to high, with reported ND determinations lowest, DNQ determinations next, and finally quantified values (if any). The order of the individual ND or DNQ determinations is unimportant. 2. The median value of the sample results is determined. If the data set has an odd number of data points, then the median is the middle value. If the data set has an even number of data points, then the median is the average of the two values around the middle unless one or both of the points are ND or DNQ, in which case the median value is the lowest of the two data points where DNQ is lower than a quantified value and ND is lower than DNQ. Annual Averages If the monthly data are all detected, an arithmetic average is calculated. If both detected and ND and/or DNQ data are available, each ND and DNQ value is averaged as a zero with the detected values. If an average of zero is calculated it will be reported as an average of ND. 4. PERMIT LIMITS A single plant may have several permits and several sets of limits, which, at a maximum, consist of the following: NPDES Permit Limits for discharge to navigable waterways. Waste Discharge Requirements for disposal to sites other than those covered by NPDES requirements (e.g., Lancaster and Palmdale WRPs). Reuse Permit Limits for nonpotable use in irrigation, impoundments, etc. Recharge Limits for groundwater replenishment in the Montebello Forebay. Reuse permit limits are not shown in the effluent table. The permits limits may be expressed in terms of an instantaneous maximum, daily average, 7-day average, weekly average, 30-day average, monthly average, and/or 12-month average. 5. PERFORMANCE GOALS The JWPCP NPDES permit includes effluent quality performance goals for 69 constituents. Selected effluent quality performance goals were assigned for constituents that are regularly detected, and were numerically set using effluent performance data for the period of November 2002 to August 2005 to determine the 95th percentile of the normal distribution. Other constituents that were not detected were assigned performance goals five times (for carcinogens and marine aquatic life toxicants) or ten times (for noncarcinogens) the minimum reporting limits in the 2004 annual report. In other cases, the maximum detected effluent concentration from November 2002 to August 2005 was prescribed as the performance goal. The performance goals are intended to reflect extreme (i.e., 95th percentile) historical values in plant effluent quality, which resulted from normal variability in the plant operation, the influent water quality, etc. The performance goals are not intended to determine compliance. Instead, the objective of the performance goals is to monitor plant performance by comparing effluent water quality data to the performance goal. For example, a single exceedance of a performance goal may be the result of normal 2

5 Wastewater Monitoring Data variability in the data, since such an exceedance can be expected occasionally (i.e., 5 percent of the time) for performance goals set at the 95th percentile. However, if an exceedance of the same goal persists, it may indicate a substantial change in plant performance, influent quality, or other causes not explained by normal and expected variability. In such cases, the JWPCP permit requirements state that the discharger must investigate the reason for the continuing exceedance of the performance goal. 3

Box 4998, Whittier, CA Telephone: (562) , extension 2824 Ownership Status: Publicly Owned Treatment Works FACILITY INFORMATION Name: Joint Water Pollution Control Plant (JWPCP) Location: S. Figueroa Street, Carson, CA Telephone: (310) NPDES Number: CA Capacity/Influent Flow: 400 MGD / 263 MGD BIOSOLIDS INFORMATION Treatment: Primary and thickened waste activated sludges were anaerobically digested at an average temperature of 96.1 degrees Fahrenheit and detention time of 19 days. Volatile solids destruction averaged 53% and digested biosolids were dewatered to approximately 29% total solids via scroll centrifuges. Dewatered biosolids were transported to various reuse or disposal sites as summarized on page 4 and described on pages The facility also co-digested 7,264 wet tons (865 dry metric tons, estimated) of food waste. Quantities Generated: 443,858 wet tons = 128,719 dry tons = 116,772 dry metric tons (1,216 wet tons per day = 353 dry tons per day = 320 dry metric tons per day) Digester cleanings = 2,534 wet tons = 667 dry tons (estimated) hauled off site for landfill disposal. Monitoring/Frequency: Monthly average digester performance for Class B time/temperature criteria and VSD (using daily temperatures and weekly volatile solids percentages). Monthly 24-hour composite samples for Table 1/Table 3 metals. Quarterly 24-hour composite samples for California Title 22 STLC analyses. Semi-Annual 24-hour composite samples for priority pollutants. Sample Type: Quality: Digested, dewatered biosolids. The location of sample collection is immediately downstream of dewatering via centrifuges. Class B pathogen reduction requirements of (b)(3) were met for the entire year via Process to Significantly Reduce Pathogens (PSRP) criteria (time/temperature) for anaerobic digestion. 1

24 U.S. EPA REGION 9 February 19, 2015 Vector Attraction Reduction requirements were met per (b)(1) for the entire year. No samples exceeded Table 1 and Table 3 metal concentrations. Results for the reporting period are shown on page 3; additional metals data are presented in Attachment A. Samples were characterized as non-hazardous per the California Title 22 Waste Extraction Test. Data are presented in Attachment A. 2

Volatile solids destruction averaged 71% and digested biosolids were dewatered to approximately 18.5% total solids via scroll centrifuges. Dewatered biosolids were further dried in concrete drying beds prior to being transported for reuse. Quantity Generated: Approximately 12,200 wet tons = 2,257 dry tons = 2,048 dry metric tons in There were no digester cleanings generated for the year. Quantity Land Applied: Approximately 3,363 wet tons were land applied by Terra Renewal. Quantity Composted: Approximately 8,837 wet tons were composted by Nursery Products, LLC. Monitoring/Frequency: Monthly average digester performance for Class B time/temperature criteria and VSD (using daily temperatures and weekly volatile solids percentages). Bi-Monthly composite samples for Table 1/Table 3 metals. Sample Type: Quality: Digested biosolids prior to dewatering. Class B pathogen reduction requirements of (b)(3) were met for the entire year via Process to Significantly Reduce Pathogens (PSRP) criteria (time/temperature) for anaerobic digestion. 1

55 U.S. EPA REGION 9 February 19, 2015 Vector Attraction Reduction requirements were met per (b)(1) for the entire year. No samples exceeded Table 1 and Table 3 metals concentrations. Results for the reporting period are shown on page 3. Data are presented in Attachment A. 2
