The Division will review the first six months of <br />eta and determine if a waiver of numeric limitations can be granted based <br />the salt-load to the river 6eiag Less than oat ton/day (or 350 <br />ins/year). If a waiver is not granted, then the permittee has an <br />iditional six months to submit a report in accordance with the salinity <br />gulations, addressing economic Eeaaability of salt-removal.
