1.0 INTRODUCTION

The following work plan is proposed pursuant to Administrative Order Docket #1-93-1055 and recommendations made by EPA Region 1 during a meeting held on March 22, 1994 and EPA's follow-up letter, dated May 5, 1994. The meeting was held in response to a series of combustible gas detections recorded by the methane detection system installed in the basement of 278 Rose Hill Road, South Kingstown, Rhode Island. During the meeting, several response actions to mitigate the occurrence of combustible gas were discussed. These actions included: 1) installing a radon styled sub-slab ventilation system, 2) sealing all cracks in the foundation and 3) moving the exterior gas sensor into the basement area to monitor potential levels of combustible gas.

This work plan presents an active sub-slab ventilation system design based upon guidance provided in EPA's Radon Reduction Techniques for Existing Detached Houses, Technical Guidance, EPA Document EPA/625/R-93/Oil (EPA TG). Also included are the procedures for sealing the foundation and repositioning the existing exterior gas sensor to inside the basement.

2.0 PURPOSE AND DESCRIPTION

Methane gas is believed to be migrating into the building from adjacent sources and is accumulating within the basement of the structure. The purpose of the proposed work is two fold. First, sealing the foundation coupled with the gas mitigation system will work to reduce the potential for migration of methane into the basement of the dwelling. Second, repositioning the exterior sensor into the basement will allow the existing strip chart to record future detection events and detection levels. The strip chart recording will show the relative concentrations of the detected gasses over time. This data must be collected to evaluate potential risks.

The subject building is a split entry wooden structure approximately 24 by 50 feet in area. The basement is an embankment foundation constructed of poured concrete. The front and sides of the building are near ground level. The ground level rises from front to back with the rear of the foundation approximately four feet below grade. The building is serviced by Town water and by a private septic system. Town water service enters the building through the floor of the foundation near the rear right hand comer of the building. Combustible gasses have been detected where the water service enters the building and at several cracks in the floor of the foundation.

*

The building is located in an area known for extensive sand and gravel deposits. Shallow on-site excavations have encountered coarse sand and gravel deposits with occasional cobbles to

a minimum depth of seven feet. Therefore, soils beneath the foundation are assumed to be permeable, well drained and be in good communication with respect to soil gas flow. The depth to ground water has not been measured at the site, however, it is assumed to be approximately 15 feet below grade based upon observations of the local area.

3.0 PROJECT DESIGN

This project has three components; installing a radon styled sub-slab ventilation system; sealing all cracks in the foundation; and moving the exterior gas sensor into the basement area to monitor potential levels of combustible gas. The following section discusses each component in more detail.

3.1 ACTIVE SUB-SLAB VENTILATION SYSTEM

Two basic designs have been considered as appropriate methane mitigation systems for the subject building. The first, active sub-slab depressurization (ASD), uses a fan to create negative pressure (suction) beneath the foundation. If the pressure under the foundation is negative with respect to that inside the house clean air will flow from the house through the foundation into the surrounding soils. The rate and volumes of air flow will be proportional to the number of cracks in the foundation. The negative pressure also draws air in from around the foundation creating soil ventilation directly beneath the foundation slab. A potential drawback from this system is that it may result in drawing methane gas towards the building before venting it, thereby reducing the effectiveness of the system. This type system is commonly used for controlling small quantities of radon gas. The second, active sub-slab pressurization (ASP), uses a fan to create a positive pressure (blowing) beneath the foundation. This type of system works to prevent the migration of soil gasses towards the foundation by creating a high pressure zone beneath and around the foundation. With the area directly beneath the foundation pressurized with clean atmospheric air, air flow through the foundation will consist of clean, injected air flowing into the house. The EPA TG suggests that pressurization systems can be more effective in areas of high soil permeability then depressurization systems. However, condensation and freezing problems can occur when cold air is blown beneath the slab. Sub-slab pressurization systems can also cause elevated levels of termicides inside the building if termicides have been apply at the location.

Traditionally the ASD is employed in radon reduction projects, therefore, more design guidance and performance data are available for these systems. ASP systems have been found to be as affective as ASD systems. However, because fewer of these systems have been installed, less data are available on their performance. In designing the gas mitigation system for the subject building, the volume of combustible gas being generated and migrating towards the property, must be considered. The potential volumes of methane gases being

DRAFT •>

generated adjacent to the property will be very high with respect to similar radon projects. Without field studies and measurements available, it is unclear which system would provide the best protection. Therefore, the proposed system has been designed to be reversible. Once installed field testing will be conducted to determine which mode of operation will provide the best protection.

The system will consist of three or four sub-slab suction/pressure pits. Two pits will be located along the backside of the basement, one near the water service connection and the other at the opposite end of the building. The remaining two pits may be located on either side of the staircase that leads upstairs. The suction/pressure pits will be excavated to a minimum size of 12' by 12" using a wet/dry vacuum cleaner. A suction point constructed of 2" schedule 40 PVC tubing will be inserted into each pit and sealed at the foundation so that air leakage does not occur. To control air flow rates at the suction/pressure points, in line valves will be placed near the points as necessary. The suction points will be connected to a 4" Schedule 40 PVC pipe which will act as a manifold. The 4" pipe will exit the building and connect to an explosion proof EG&G Rotron regenerative blower, Model EN 404, 303 or 101, to move air through the system (Appendix B). The blower fan will be connected to the 4" manifold pipe with a flexible connector to minimize system noise. An in-line muffler will also be installed to reduce system noise (Appendix B). The blower fan will also be connected to an inlet/outlet pipe which will run up the outside of the building to a point 10 feet above grade and 10 feet from any openings such as windows, doors and vents. The inlet/outlet pipe will be fitted with a sampling port and a rain shield and/or outlet muffler/filter.

Figures 1, 2, and 3 in Appendix A present possible piping configurations as described above. The goal when installing such a system is to maximize efficiency by minimizing the length of the suction pipes and the number of bends in the piping system. Also, care will be taken to ensure that condensation drains are effectively placed so that excessive condensation build up does not occur. The most effective and unobtrusive configuration will be determined in the field during installation.

Once the system is installed, the effectiveness of the suction points can be evaluated using a micromanometer. Sub-slab depressurization or pressurization can be measured with the micromanometer to determine the effective radius of each suction/pressure point. The target goal for this application will'be a depressurization/pressurization of between .01 and .02 inches of Water Gauge (WG).r

A major divergence between the proposed system and a typical radon ventilation system is the fan. Because an explosion proof fan has been required for the project, a regenerative blower is necessary. Regenerative blowers are high-suction low volume fans as opposed to the low-suction high volume centrifugal in-line tubular fans commonly used in residential radon mitigation applications. Regenerate blowers appropriately sized for this application have flow rates of approximately 50 to 60 cubic feet per minute (cfm) at zero static pressure and are capable of developing up to 35 inches WG pressure or suction. Centrifical fans used radon applications typically move from 100 cfm up to 270 cfm at zero static head and develop only

DRAFT 3

one to two inches WG. High-suction units have the disadvantages of higher capital costs, higher operating costs, higher noise level and mechanical failure if air flow exceed their static capacity. Typically, regenerative blowers are more suitable for soils with low permeability than those which with high permeability because of the radius of influence developed by the suction points. In highly permeable soils, such as those observed at the site, the radius of influence of each suction/pressure pit will be smaller using the regenerative blower verses the centrifical fan. Additional suction/pressure pits maybe necessary to extend the influence of the fan over the entire basement area.

To reduce the potential noise generated by the fan, in-line and outlet/intake mufflers have been proposed. A noise reducing air filter for the inlet pipe will also be necessary for the ASP system. The fan will be mounted outside of the building in an insulated, enclosed unit similar to a dog house. Where possible, soft or flexible connectors will be used to connect piping to the structure. The system will also be fitted with two pressure gauges to monitor the performance of the system.

3.2 BASEMENT SEALING

Sealing the basement is critical to reducing leakage when using a high-suction low volume blower. In general, the foundation of the building is in good condition. Although several thin cracks have been observed at various locations, none are thought to be significant. Prior to the initiation of the basement sealing activities, the foundation floor and below grade walls will be inspected for cracks and damage. All visible cracks will be marked with chalk and later sealed with expansion cement and/or suitable caulking compound. Special attention will be paid to the water service entrance and the septic discharge pipe areas where combustible gases are known to be entering. Once the sealants have cured and the sub-slab ventilation system is installed, the foundation floor and walls will be painted with a suitable cement sealant paint. Two coats will be applied as necessary to ensure an even finish.

3.3 GAS DETECTION SYSTEM

Two gas sensors are currently in operation at the subject building. An exterior sensor, Serbia Monitor Corporation (SMC) Model 4101-02 Combustible Gas Sensor, is installed approximately four feet below grade, in a six inch gas well. This sensor is coupled to a Rustrak 2" strip chart recorder and an illumination alarm via a SMC Model 4011-00 Single Channel Controller. The second sensor, a SMC Model 2001-10 is located in the basement in the first floor joists. This sensor is coupled to an audible alarm via the same SMC controller. The alarm set point for both sensors is approximately 1000 ppm of methane.

Under this work plan, the existing gas detection system will be reconfigured to provide continuous recording of interior combustible gas levels and reduce the occurrence of false positive alarm events. The exterior sensor will be removed from the gas well and installed on

DRAFT 4

the ceiling of the basement. The sensor will remain coupled to the strip chart recorder and the illumination alarm will be replaced with an audible alarm. The second sensor SMC Model 2001-10 will be disconnected and stored.

After the sensor is repositioned and the system is reactivated for a 24 hour period, the system will be recalibrated. Base upon EPA's recommendation for a more feasible detection level, the alarm set point will be reset to approximately 2500 ppm methane. If a higher alarm set point is required, the system will have to be disconnected and returned to the factory for internal adjustments.

4.0 OPERATIONAL COSTS

The annual costs for operating the sub-slab ventilation system have been estimated based upon the power consumption and heat/cooling losses as describe by EPA's TG. System operational costs are predicted to be approximately $450.00 to $600 per year when the system is operating full time.
