           The only affordable repair option
        is to construct a temporary chimney
        which will take 12 months to build. It
        is estimated that repairs would take
        two years to complete, and cost about
        R250 million. Tender processes must
        be approved, a contract must be drawn
        up and signed, and the necessary
        resources must be made available.
           In 2020, Barbara Creecy, the
        Minister of Forestry, Fisheries and the
        Environment, signed an amendment
        to the National Environmental
        Management: Air Quality Act 39
        of 2004, stating that despite new
        regulations allowing 500 mg/Nm  of
                                 3
        SO 2 emission from industries such
        as coal-fired power plants, “existing
        plants shall comply with a new plant

                               3
        sulphur dioxide (SO 2).”
           The initial amendment from 3500 mg/
        Nm  to 500 mg/Nm , and the amendment
                       3

        for existing industries to comply with
                  3
        1000 mg/Nm  was surrounded by
        controversy, as environmentalists
        argued the emission allowance
        exception was too high – double the first
        amendment – and industries affected
        by it said it was unreasonable to expect
        immediate compliance, given the state
        of the South African economy. As a
        result, postponement or suspension
        of compliance applications were made
        available.
