The City continued to haul wastes to Capas, Tarlac for almost three (3) years, from July 2008 to April 2011.  In between, were gaps in the hauling as the City ran out of funds in the hauling cost and in the delay of the approval of the City Council of hauling cost.  Within the same period, the City Government continue to implement the closure and rehabilitation works at the dump and disposed wastes at some void portions of the dump created by their closure activities. On April 11, 2011, the City ceased hauling wastes to the Metro Clark Sanitary Landfill at Capas, Tarlac.

On October 2009, to fully close and rehabilitate the Irisan dump facility, the City made revisions of the closure plan. Integral component of the plan is the construction of a wall that would expand an area within the down slope southern portion of the dump.   (Project Title: Irisan Dumpsite Rehabilitation) Subsequently, on November 13, 2009; the City Government requested the National Solid Waste Management Commission-Secretariat (NSWMC-S) for the use of the expanded area using residuals as backfilling materials.

            During the onslaught of typhoon ?Mina? on August 27, 2011; a trash slide occurred at the Irisan garbage dump facility within Purok 17, Irisan, Baguio City.  The portion of the retaining wall at the dump collapsed and about 30,000 tons of wastes cascaded two hundred (200) meters into a gulley and down to Km. 5, Asin Road, Baguio City.

This caused the death of six (6) persons and about twenty (20) residential houses and make shifts were damaged.  The wastes also blocked the Asin Road and was closed to traffic for four (4) days. Public health issues as well as environmental concerns attributed to the trashslide are continuously being raised by residents and different sectors of Baguio City and Tuba, Benguet.
