J. Hunter & Associates regarding your client's request for an extension to submit the investigative report for the site. At our 3 August 1994 meeting, we discussed the need for further investigation at the facility to define the extent of subsurface contamination caused by the illegal disposal of hazardous waste into a septic tank and leachfield. At the meeting, we concluded that the property owners, Mr. William Miles and Ms. Patricia Nolet, would be responsible for conducting the next phase of investigation which would include looking at surrounding properties and past on-site operations, surveying for underground tanks, drilling soil borings and installing ground water monitoring wells. The goal of this work was to define the full extent of contaminated soil and ground water. A work plan was due by 16 September 1994. In September 1994, prior to submitting the work plan, the property owners took the initiative to locate and remove a number of underground storage tanks and associated piping. Extensive soil contamination found in the vicinity of the tanks and piping was left in place to be addressed at a later date. Also at that time you submitted a request to extend the submittal date of the work plan to 16 October 1994; the request was granted. On 15 November 1994, Wm. J. Hunter & Associates submitted a work plan. The work plan only proposed one ground water monitoring well which would have been inadequate to define the extent of contamination. The Board requested that by 6 January 1995 a new work plan be submitted which would propose at least three monitoring wells located in appropriate locations to begin defining the extent of contamination related to the underground tanks and the old leachfield. The 14 February 1995 revised work plan was subsequently approved. The work plan proposed four monitoring wells and four soil borings at locations appropriate to begin defining the extent of soil and ground water contamination present throughout the site's subsurface. Based on the schedule in the work plan, a report was due 1 June 1995.
