One crucial component of the Integrated Persistent Organic Pollutants (IPOPs) Management Project is the reduction of releases of Unintentionally-Produced Persistent Organic Pollutants (UPOPs) in critical areas. Such is the case of a dumpsite in Barangay Banquerohan, Legazpi City. To achieve this goal, a Safe Closure and Rehabilitation Plan (SCRP) for Banquerohan dumpsite has been developed and implemented.
The SCRP adopts the Best Available Technology (BAT) and Best Environmental Practices (BEP). It encompasses activities such as building access road with drainage system, site clearing, waste profiling, application of clay and topsoil cover, perimeter slope protection, leachate collection and recirculation, gas venting, monitoring wells and perimeter fencing.
Initial report of SCRP implementation as of the first week of April 2016 showed that 67.55% of the 23,220 sq.m. had already been covered by earthworks. Building of structural concrete and boundary fence was on track. Likewise, the establishment of access road and installation of a storm drainage system were underway.
The UPOPs are seen to be largely produced from open burning of wastes in dumpsite, landfill fires and backyard burning of municipal wastes by households and recyclers. Emissions of these pollutants not only linger in the atmosphere but eventually contaminate the environment, i.e. air, soil and sediments. Substances such as dioxins and furans are harmful in a way that they tend to remain in the environment for very long durations. They also accumulate in plants and animals, which humans consume, thus, elevate health risks like cancer and birth defects. #
