deficiencies, the municipality may accept submission of modifications.
C.
The municipality shall notify the applicant, in writing, within 45

A modification to a submitted SWM site plan and report for a

or techniques or that involves the relocation or redesign of stormwater
management facilities or that is necessary because soil or other conditions
are not as stated on the SWM site plan, as determined by the municipality,

of validity shall commence on the date the municipality signs the
approval for a SWM site plan. If stormwater management facilities
included in the approved SWM site plan have not been constructed,
or if a record drawing of these facilities has not been approved within
this time, then the municipality may consider the SWM site plan disapproved
and may revoke any and all permits or approvals.
A.
