for receiving electronic NPDES data [see 40 CFR 127.2(b)].

temporary waiver shall not exceed 5 years and shall thereupon expire. At such time,monitoring data
and reports shall be submitted electronically to the Division unless the permittee re-applies for and is
granted a new temporary electronic reporting waiver by the Division. Approved electronic reporting

submit monitoring data and reports on paper to the Division for the period that the approved
reporting waiver request is effective.
