SECTION 252:690-3-12. Background monitoring and frequency

Latest version.

When effluent limits have not been established and a complete background data set that meets the requirements of OAC 252:690-3-11 is not available, , the appropriate BT/C equation in Appendix J shall be used to determine whether background monitoring is required. If the BT/C ratio is less than or equal to the (BT/C)max value using the appropriate equation in Appendix J, background monitoring is required and the monitoring frequency must be sufficient to provide at least ten (10) data points over a period of one year. The collected background data shall be used in conjunction with the effluent data to determine if there is reasonable potential for the effluent to violate water quality standards.
