<br />2 Assumes a soil source of calcium from time (CaCO3) or silicates; no precipitation of magnesium, and partial
<br />pressure of CO2 near the soil surface (Pc02) is 0.0007 atmospheres.
<br />3 Ca,(, HCO3, Ca are reported in meq/l; EC is in dS/m (deciSiemens per meter).
<br />Because values will not always be quantified at the exact EC or HCO3 /Ca" ratio in the table, the resulting Ca,
<br />must be determined based on the closest value to the calculated value. For example, for a calculated EC of 2.45
<br />dS/m, the column for the EC of 2.0 would be used. However, for a calculated EC of 5.1, the corresponding column
<br />for the EC of 6.0 would be used. Similarly, for a HCO3 /Ca" ratio of 25.1, the row for the 30 ratio would be used.
<br />The Division acknowledges that some effluents may have electrical conductivity levels that fall outside of this
<br />table, and others have bicarbonate to calcium ratios that fall outside this table. For example, some data reflect
<br />HCO3 /Ca" ratios greater than 30 due to bicarbonate concentrations reported greater than 1000 mg/l versus
<br />calcium concentrations generally less than 10 mg/l (i.e., corresponding to HCO3 /Ca" ratios greater than 100).
<br />Despite these high values exceeding the chart's boundaries, it is noted that the higher the HCO3 /Ca" ratio, the
<br />greater the SAR-adj. Thus, using the Ca,, values corresponding to the final row containing bicarbonate/ calcium
<br />ratios of 30, the permittee will actually calculate an SAR-adj that is less than the value calculated if additional
<br />rows reflecting HCO3 /Ca" ratios of greater than 100 were added.
<br />32. "Seven (7) day average" means, with the exception of fecal coliform or E. coli bacteria (see geometric mean), the
<br />arithmetic mean of all samples collected in a seven (7) consecutive day period. Such seven (7) day averages shall
<br />be calculated for all calendar weeks, which are defined as beginning on Sunday and ending on Saturday. If the
<br />calendar week overlaps two months (i.e. the Sunday is in one month and the Saturday in the following month), the
<br />seven (7) day average calculated for that calendar week shall be associated with the month that contains the
<br />Saturday. Samples may not be used for more than one (1) reporting period. (See the "Analytical and Sampling
<br />Methods for Monitoring and Reporting Section in Part I.D.3 for guidance on calculating averages and reporting
<br />analytical results that are less than the PQL).
<br />33. "Significant spills and leaks" - include, but are not limited to, releases of oil or hazardous substances in excess of
<br />quantities that are reportable under CWA Section 311 (see 40 CFR 110.6 and 40 CFR 117.21) or Section 102 of the
<br />Comprehensive Environment at Response, Compensation and Liability Act (CERCLA), 42 USC 59602. This permit does
<br />not relieve the permittee of the reporting requirements of 40 CFR 110, 40 CFR 117, and 40 CFR 302 relating to
<br />spills or other releases of oils or hazardous substances.
<br />34. "Stormwater" - stormwater runoff, snow melt runoff, and surface runoff and drainage. See 5 CCR 1002-61.2(103).
<br />35. "Stormwater Discharges Associated with Industrial Activity" - the discharge from any conveyance that is used for
<br />collecting and conveying stormwater and which is directly related to manufacturing, processing or raw materials
<br />storage areas at an industrial plant. Except for the provision of 61.3(2)(c) that addresses construction activities
<br />associated with oil and gas operations or facilities, the term does not include discharges from facilities or activities
<br />excluded from the NPDES program under 40 CFR Part 122 or the CDPS program under Regulation No. 61.
<br />For the categories of industries identified in this permit, the term includes, but is not limited to, stormwater
<br />discharges from industrial plant yards; immediate access roads and rail lines used or traveled by carriers of raw
<br />materials, manufactured products, waste material, or by-products used or created by the facility; material
<br />handling sites; refuse sites; sites used for the application or disposal of process waste waters); sites used for the
<br />storage and maintenance of material handling equipment; sites used for residual treatment, storage, or disposal;
