recommend ways to improve the effectiveness of the program and advise the Department
whether the City has met its obligations under 310 CMR 60.04(4)(a). The Oversight
Committee shall submit its advice to the Department within 60 days of receipt of a
Monitoring and Demonstration Report.
(c) If the Oversight Committee, based on its review of the Monitoring and Demonstration
Report, advises the Department that the City has met its obligations under 310 CMR

finding of adequacy or inadequacy, depending on the results of the review and public
comment.
(e) If the Report is found inadequate pursuant to 310 CMR 60.04(12), and notwithstanding
a request for an adjudicatory hearing, the City shall resolve the inadequacies to the
satisfaction of the Department prior to issuing any new commercial parking space permits
for spaces in excess of 13,452. If the City and the Department are unable to resolve their
differences within 60 days, the City may request an adjudicatory hearing on the Department's
determination pursuant to M.G.L c. 21A and c. 30A.
(f) The City has the option to submit a Monitoring and Demonstration Report to the
Department in years when such a report is not otherwise required. The City shall submit a
Monitoring and Demonstration Report to the Department and the Oversight Committee at
such time when there are 13,377 commercial parking spaces permitted in the City in order
to identify how the air emissions associated with new commercial parking spaces in excess
of 13,452 will be offset.

regulation achieves results in excess of the goals established by the SlP for such program or
regulation.
(b) The failure of the City of Cambridge to comply with the requirements of 310 CMR
60.04 may be the cause for the Department to make a finding of non-conformity under
