§ 90.100. Nutrients and soil amendments.
(a) Nutrients and soil amendments, in the amounts determined by soil tests, shall be applied to the surface soil layer so that it supports the approved postdisposal land use and meets the revegetation requirements of § § 90.151—90.157, 90.159 and 90.160.
(b) All soil tests shall be performed using standard methods approved by the Department.

An alternate material of equivalent neutralizing effect may be employed.
(d) The use of fly ash and sewage sludge as soil amendments may be approved by the Department if demonstrated to be a suitable soil amendment and the requirements of Articles VII—IX (relating to hazardous waste management; municipal waste management; and residual waste management) are met.
