You have demonstrated initial compliance if E is greater than or equal to 90 percent.[GRAPHIC] [TIFF OMITTED] TR14JY06.031 Where: E = destruction efficiency of total PSHAP and SHAP for the biological
treatment unit including the equalization unit, neutralization
unit, and/or clarifier, percent;QMWa = mass flow rate of total PSHAP and SHAP compounds
entering the equalization unit (or whichever of the three
types of units is first), kilograms per hour (kg/hr); QMGe = mass flow rate of total PSHAP and SHAP compounds
emitted from the equalization unit, kg/hr;QMGn = mass flow rate of total PSHAP and SHAP compounds

(B) You may elect to assume fbio is zero for any compounds on List 2 of table 36 in subpart G.
(v) Determine QMGe, QMGn, and QMGc using EPA's WATER9 model or the most recent update to this model, and conduct testing or use other procedures to validate the modeling results.
(vi) Submit the data and results of your demonstration, including both a description of and the results of your WATER9 modeling validation procedures, in your notification of compliance status report as specified in Sec. 63.2520(d)(2)(ii).
(3) As an alternative to the venting requirements in Sec. 63.136(e)(2)(ii)(A), a lift station with a volume larger than 10,000 gal may have openings necessary for proper venting of the lift station. The size and other design characteristics of these openings may be established based on manufacturer recommendations or engineering judgment for venting under normal operating conditions. You must describe the design of such openings and your supporting calculations and other rationale in your notification of compliance status report.
(4) For any wastewater streams that are Group 1 for both PSHAP and SHAP, you may elect to meet the requirements specified in table 7 to this subpart for the PSHAP and then comply with paragraphs (n)(1) through (3) of this section for the SHAP in the wastewater system. You may determine the SHAP mass removal rate, in kg/hr, in treatment units that are used to meet the requirements for PSHAP and add this amount to both the numerator and denominator in Equation 1 of this section.
