* Facility required to conduct detailed testing for these cooling towers.

1 Facility did not provide a copy of the test report.

2 Red text indicates that the default values for flows specified in the method, atmospheric P, and average ambient temperature were used. For cooling water tests conducted in the Summer of 2011, assumed that the apparatus temperature was at least 90F (32C).

3 The facility calculated the concentration in the water based on the air concentration, and provided the value.

4 Compare to measured water concentration, below.

5 Compound was BDL in the measured air.

6 The facility calculated the mass emission rate and provided the value.

7 The facility provided calculated values for the water concentration and the mass emission rate, but there appeared to be a problem with the calculation (facility used 2.5 mL/min for the air flow rather than 2,500 mL/min).

8 Measured air concentration is not provided as methane; in determining the water concentration and the mass emission rate, the air concentration was converted to methane.

** Not a HAP.
