Site-specific Limitations <br />Site-specific limitations for a parameter may be added on a case-by-case basis that are equivalent to the Basic Standards <br />and Methodologies for Surface Water, or Regulation for Effluent Limitations, or any other applicable regulation, and <br />would be specified in the certification along with the appropriate monitoring frequencies. <br />3. Onetime Sampling Analysis for Metals <br />The Division may request a onetime sampling and analysis for specific or all inclusive metals parameters on a site <br />specific/ discharge specific basis. The permittee will be required to submit these results to the permit writer identified on <br />the certification. The Division will then review the data to determine if any certification amendments are necessary based <br />on the effluent monitoring results. <br />4.
