%PL = [(PL-PS)/(PT-PS)] * 100 (Eq. 3)
Where:
%PL = percent leaking pumps
PL = number of pumps found leaking as determined through periodic monitoring as required in paragraphs (c)(2)(i) and (ii) of this section.
PT = total pumps in organic HAP service, including those meeting the criteria in paragraphs (c)(5) and (6) of this section.
PS = number of pumps in a continuous process leaking within 1 quarter of startup during the current monitoring period.
where:
%VLO = overall performance of total valves in the applicable process or group of processes
%VLi = percent leaking valves in subgroup i, most recent value calculated according to the procedures in paragraphs (e)(6)(ii) and (iii) of this section
Vi = number of valves in subgroup i
%VL = [VL/VT] * 100 (Eq. 5)
Where:
%VL = percent leaking valves as determined through periodic monitoring required in paragraphs (e)(2) through (4) of this section.
VT = total valves monitored, in a monitoring period excluding valves monitored as required by (e)(7)(iii) of this section
