Presentation "The TPC Perspective" by Professional Service Industries (PSI) Inc, Eugene, OR

The data are assumed to represent the state of the world after CARB 1 went into effect (before CARB 2). Because emission levels are presented on charts (not tables), there is uncertainty about the values.

Canada is assumed to have the same emission levels as these in the U.S., i.e. come into full compliance with CARB 2. Facilities that met CARB 1 level at the time when CARB 1 was in effect are assumed to get to CARB 2 level when the CARB 2 requirements are in effect.

Converted the data from charts to excel tables by approximating the number of tests (axis Y). Estimated the fraction of observations that meet CARB 1 and CARB 2 requirements using midpoint of intervals to make CARB status determinations. Made the following adjustment to the data in order to account for the changes in emission levels when CARB 2 goes into effect. Adjusted the number of observations to account for those facilities that made changes to meet CARB 2 requirements. Only those facilities that met CARB 1 are brought up to the highest emission level under CARB 2. This assumes that those facilities that made an effort to meet CARB 1 (when CARB 1 went in effect) will meet CARB 2.**HCHO Emissions (ppm) and frequency for HWPW**
