SSWM Subsidiary Receives Official Request for Statewide Permitting and Municipal Area Health Risk Assessment in Puebla, Mexico.

ETI Supports State's Environmental Infrastructure Development

CARLSBAD, Calif. -- Sub-Surface Waste Management of Delaware, Inc. (OTCBB:SSWM), announced that its Mexico subsidiary company Environmental Tec International, S.A. de C.V. (ETI) received a letter of request from the State of Puebla's Secretary of the Environment, Francisco Castillo Montemayor, to contract with ETI to address two separate missions.

The first project is to establish protocols to train enforcement staff and manage the implementation of a Statewide environmental waste emissions permitting program to be funded from the collection of annual fees based upon actual waste generator releases exceeding regulatory standards of toxics to air, soil and water media.

The second assignment is to design, cost and implement as soon as possible a comprehensive human health risk assessment for the City of TehuacEin, Puebla's second largest city with a population of 360,000. In the nineties, TehuacEin saw a flood of textile maquiladoras set up shop in the city and surrounding areas to put together blue jeans for export. Environmentally, the maquiladoras used up huge amounts of the underground water reserves stone-washing jeans and the water that passes through the city is tinted blue and is full of chemicals. TehuacEin is also home to some of Latin America's largest poultry, eggs and swine producers generating significant impacts as well. The ETI program will characterize the area's industry emissions to air, soil and water coupled with data confirmation from affected human population groups using blood and urine collection & analysis to estimate the chance that contact with chemicals will harm people now or in the future. This process will provide numbers that show how great (or small) the risks may be. It also points to who is at risk, what is causing the risk, and how accurate are the numbers.

Bruce Beattie, CEO of SSWM, stated, "These two new assignments represent a milestone achievement for the people of the State of Puebla to receive the benefits inherent in the establishment of critical and timely environmental enforcement based upon documented risks to public health, safety and exposure from the by-products of industrial activities. We are creating a generator pays, fee-based program that will support the permanent establishment of trained regulatory staff to serve the enforcement of both Federal and State environmental regulations. Further, ETI has received these new assignments due to the very positive reception to our recent report submittal on the data collected from the environmental site assessment of the Pemex Bulk Storage Facility at the entrance of the City of Puebla."
