Mr. Jack Badey, UniFirst -2- 26 May 2011 Contingency Plan As discussed on 18 March 2011 in a telephone conversation between Mr. Bill Aravanis of AMEC Geomatrix, and Ms. Amy Terrell of my staff, the contingency plan described in the Addendum is modified to state that if a significant and prolonged increase in dissolved organic carbon, or vinyl chloride occurs in the compliance point wells, then the contingency plan will be implemented. If either of these compounds is detected in a compliance point well, then three consecutive quarters of monitoring for these constituent(s) in the compliance well(s) and in the background wells will be conducted. If the background concentration is exceeded and sustained in the compliance well(s) for three consecutive quarters, then UniFirst will provide a work plan to address the particular exceedance. The work plan could include aeration, a pH adjustment, introduction of dehalococcoides bacteria, or continued monitoring, depending upon the nature of the exceedance. On 24 May 2011, in a telephone call, Mr. Bill Aravanis of AMEC Geomatrix stated that the Monitoring and Reporting program identified a due date of 31 May 2011 to submit a proposal to develop background concentrations. He suggested that this date be extended since it falls so close to the date of this Notice of Applicability. The Monitoring and Reporting Program now reflects a due date of 1 August 2011 for the proposal. No other comments were received during the public comment period ending 23 May 2011 . General Information: 1. The project will be operated in accordance with the requirements contained in the General Order and in accordance with the information submitted in the Notice of Intent. 2. The required annual fee (as specified in the annual billing you will receive from the State Water Resources Control Board) shall be submitted until this Notice of Applicability is officially revoked. 3. Injection of materials other than HRC and HRC Primer into the subsurface is prohibited. 4. Failure to abide by the conditions of the General Order could result in an enforcement action as authorized by provisions of the California Water Code. 5. The project will implement the final contingency plan included as part of the 21 February 2011 Addendum, and as refined above, within 60 days of it being triggered.
