CITY OF SANTA ANA SPECIFICATIONS water pollution prevention measures are inadequate. No further work shall be performed on the items until the water pollution prevention measures are adequate and, if also required, a revised SWPPP and /or WWECP has been accepted. The Engineer will notify the Contractor of the acceptance or rejection of any submitted or revised SWPPP and /or WWECP in not more than 5 working days. The City will not be liable to the Contractor for failure to accept all or any portion of an originally submitted or revised SWPPP and /or WWECP, nor for any delays to the work due to the Contractor's failure to submit an acceptable SWPPP and /or WWECP. The Contractor may request the Engineer to waive the requirement for submission of a SWPPP and /or WWECP when the nature of the Contractor's operation is such that pollution and /or erosion is not likely to occur. Waiver of this requirement will not relieve the Contractor from responsibility for compliance with the other provisions of this section. Waiver of the requirement for a SWPPP and /or WWECP will not preclude requiring submittal of a SWPPP and /or WWECP at a later time if the Engineer deems it necessary because of the effect of the Contractor' operations.
