Initiate additional treatment BMPs such as off-site treatment, infiltration, <br />filtration and chemical treatment within 24 hours of the first 250 NTU <br />exceedance. <br />3. Implement additional treatment BMPs as soon as possible, but within 7 <br />days of the first Z50 NTU exceedance. <br />4.
