The work of this subprogram included (1) submitting a work plan, pollution control plans, monthly results and daily construction records of the work, and progressing reports, (2) holding discussions for farmers and landholders, (3) confirming the degree of heavy metal pollution of polluted farmlands, (4) carrying site remediation by soil dilution, self-verification, third-party-verification, fertilization, and finally (5) lifting site restriction. All work was conducted according to the contract. Besides, EPB also held discussions at regular intervals to know well the work.
