Mr. David Newton EPA Region I/RPM JFK Federal Building Boston, MA 02203

RE: Rose Hill Regional Landfill, South Kingstown, RI.

Dear Mr. Newton;

This is a summary of the events and operation and maintenance records for the combustible gas detection systems installed at 278 and 349 Rose Hill Road in South Kingstown, Rhode Island. This report covers the period from January 1,1997, through December 31, 1997.

ADMINISTRATIVE ORDER ACTIVITIES

During this reporting period, Geological Field Services, Inc. (GFS) has performed no activities related to the administrative order. On August 9,1996, EPA instructed the Town of South Kingstown to prepare summary reports on a annual basis and to correspond directly with Mr. David Newton. The last monitoring report was submitted on January 29,1997.

278 ROSE HILL ROAD

Both interior sensors were calibrated monthly during 1997. Table 1 lists all of the calibration events and results. Attachment A contains copies of the field "Maintenance Report" forms for each of the calibration events.

From January through September the system functioned with no downtime or equipment failures. In October the strip chart paper got caught up in the recorder. It was removed during the November calibration event, however, the needle was damaged and stopped deflecting when the calibration gases were applied. A new strip chart was ordered in November. A unit was received and installed in December, however, the internal electronics were incompatible with the sensor's output and the strip chart did not function properly. A replacement strip chart was received from the factory in January and was installed on January 15, 1998. At that time the system was fully repaired and was functioning with the approved specifications. During the months of October, November and December the alarm continued to function while the strip chart was removed. The alarm was not tripped during these months.

156 Tremont Street, Melrose, Massachusetts, 02176 Tel: (781) 662-9800 Fax: (781) 665-3099

The combustible gas detection system operating at 278 Rose Hill Road experienced partial down time during the fall of 1997, when the slip chart was not recording. No deviations from the Work Plan occurred during this reporting period.

There were three combustible gas detections recorded by the detection system operating at 278 Rose Hill Road during this reporting period. The first recorded event occurred on January 15, 1997, at 10:05 PM and lasted for 45 minutes. The peak detection was approximately 40 parts per million (ppm) with an average was 25 ppm. The second event occurred on January 21,1997, at 12:18 PM and lasted 11 minutes. The peak detection was approximately 36 ppm and the average was 22 ppm. The third recorded detection occurred on May 25, 1997, at 4:00 PM. This detection event lasted one hour and thirty two minutes. The peak detection was approximately 40 ppm with an average was 32 ppm.

Based upon the available data, detectable concentrations of combustible gases were detected within the basement of the dwelling three times during 1997. The maximum detected concentration was 40 ppm with an average of approximately 25 ppm. The detected concentrations were an order of magnitude plus, below the alarm set point of 1000 ppm and are not believed to represent a significant concentration.

349 ROSE HILL ROAD

The interior and exterior sensors were calibrated monthly during 1997. Table 2 lists all of the calibration events and results. Attachment B contains copies of the field "Maintenance Report" forms for each of the calibration events.

During the April calibration event, the exterior sensor calibrated with the span gas but produced a low reading on the controller (4.1) when the alarm set point calibration gas was applied. The sensor and canister of alarm calibration gas were replaced in May and the system calibrated property. The interior sensor was unplugged by the resident on April 1 after the power went out during a storm event. When the power came back the alarm automatically sounded. In June the interior sensor malfunctioned and was replaced. During August the exterior sensor was struck by lighting. The system was removed hi September, rebuilt and installed in early November. At that time the sensor calibrated and the alarms were functioning, however, the new strip chart's internal electronics were incompatible with the output of the sensor. A replacement strip chart was received from the factory in January and was installed on January 15,1998. At that time the system was fully repaired and was functioning with the approved specifications.

December 4 Sensor calibrated OK. Strip chart out for repairs.


January 15 Strip chart replaced. System calibrated within specifications.


The combustible gas detection system operating at 349 Rose Hill Road experienced a complete shut down during September and October of 1997. In November and December the stip chart was not recording, but the alarms were functioning. The alarms were not tripped during these months. No deviations from the Work Plan occurred during this reporting period. No deviations from the Work Plan occurred during the reporting period.

There were no combustible gas detections recorded by the exterior sensor operating at 349 Rose Hill Road during 1997. The strip chart recordings are presented in Attachment C.
