(2) The department may extend the time of compliance for any person, class of persons, municipalities or businesses upon such conditions as it may deem necessary to protect the public health and welfare if it is found that strict compliance would be unreasonable, unduly burdensome or impractical due to special physical conditions or cause or because no other alternative facility or method of handling is yet available.
