  <paragraph num="A.">
    <text>Specific Constituent Limitations for Sewage Sludge.</text>
    <paragraph num="(1)">
      <text>The following constituent limitations apply to application of sewage sludge:</text>
      <paragraph num="(a)">
        <text>Bulk sewage sludge may not be applied to the land if the concentration of any constituent in the sewage sludge exceeds the ceiling concentration for the constituent in Table 1 of §B(1) of this regulation;</text>
      </paragraph>
      <paragraph num="(b)">
        <text>Bulk sewage sludge may not be applied to agricultural or marginal land, forest, or a public contact site if either:</text>
        <paragraph num="(i)">
          <text>The cumulative loading rate for any constituent exceeds the cumulative constituent loading rate for the constituent in Table 2 of §B(2) of this regulation; or</text>
        </paragraph>
        <paragraph num="(ii)">
          <text>The concentration of any constituent in the sewage sludge exceeds the concentration for the constituent in Table 3 of §B(3) of this regulation;</text>
        </paragraph>
      </paragraph>
      <paragraph num="(c)">
        <text>Bulk sewage sludge may not be applied to a lawn or a home garden if the concentration of any constituent in the sewage sludge exceeds the concentration for the constituent in Table 3 of §B(3) of this regulation; and</text>
      </paragraph>
      <paragraph num="(d)">
        <text>Sewage sludge may not be sold or given away in a bag or other container for application to the land if:</text>
        <paragraph num="(i)">
          <text>The concentration of any constituent in the sewage sludge exceeds the concentration for the constituent in Table 3 of §B(3) of this regulation; or</text>
        </paragraph>
        <paragraph num="(ii)">
          <text>The product of the concentration of any constituent in the sewage sludge and the whole annual sewage sludge application rate for the sewage sludge causes the annual constituent loading rate for the constituent in Table 4 of §B(4) of this regulation to be exceeded.</text>
        </paragraph>
      </paragraph>
    </paragraph>
    <paragraph num="(2)">
      <text>Determination of Annual Whole Sewage Sludge Application Rate (AWSAR).</text>
      <paragraph num="(a)">
        <text>The following equation expresses the relationship between the AWSAR in metric tons per hectare per 365 day period on a dry weight basis and the annual constituent loading rate (ACLR) in kilograms per hectare per 365 day period for a constituent:</text>
      </paragraph>
      <paragraph num="(b)">
        <text>To determine the AWSAR for sewage sludge, a person shall sequentially do the following:</text>
        <paragraph num="(i)">
          <text>Step 1 — analyze a sample of the sewage sludge to determine the concentration for each of the constituents listed in Table 4 of §B(4) of this regulation;</text>
        </paragraph>
        <paragraph num="(ii)">
          <text>Step 2 — using the constituent concentrations from Step 1 and the ACLRs from Table 4 of §B(4) of this regulation, calculate an AWSAR for each constituent using Equation # 1 from §A(2)(a) of this regulation; and</text>
        </paragraph>
        <paragraph num="(iii)">
          <text>Step 3 — identify as the AWSAR for the sewage sludge the lowest AWSAR calculated in Step 2.</text>
