Operating Limits

x= 1ni=1nX1, y= 1ni=1nY1   (Eq. 1)

Where:

X₁ = the PM CPMS data points for the three runs constituting the performance test,

Y₁ = the PM concentration value for the three runs constituting the performance test, and

n = the number of data points.

R= Y1X1-z                      (Eq. 2)

Where:

R = the relative mg/dscm per milliamp for the PM CPMS,

Y₁ = the three run average mg/dscm PM concentration,

X₁ = the three run average milliamp output from the PM CPMS, and

z = the milliamp equivalent of the instrument zero paragraph (9)(b)(A) of this rule.

Ol=z+0.75(L)R                    (Eq. 3)

Where:

O_l = the operating limit for the PM CPMS on a 30-day rolling average, in milliamps.

L = the source emission limit expressed in lb/Mmbtu,

z = the instrument zero in milliamps, determined from paragraph (9)(b)(A) of this rule, and

R = the relative mg/dscm per milliamp for the PM CPMS, from Equation 3.

Oh= 1ni=1nX1                    (Eq. 4)

Where:

X1 = the PM CPMS data points for all runs i,

n = the number of data points, and

Oh = the site specific operating limit, in milliamps.

Initial and Annual Performance Testing

C_adj = C_meas (20.9 - 7)/(20.9 - %O₂)                (Eq. 5)

Where: C_adj = pollutant concentration adjusted to 7 percent oxygen;

C_meas = pollutant concentration measured on a dry basis;

(20.9 - 7) = 20.9 percent oxygen - 7 percent oxygen (defined oxygen correction basis);

20.9 = oxygen concentration in air, percent; and

%O₂ = oxygen concentration measured on a dry basis, percent.
