These crimes include knowing and wilful offenses specified in Titles 13, 44, and 48, or any knowing and wilful crime arising out of or in connection with environmental laws, or any attempt, aiding, abetting, solicitation, or conspiracy to commit a knowing and wilful crime involving the environment if the anticipated actual damages including, but not limited to, the cost of remediation, are two million dollars or more, as certified by an independent environmental engineer who shall be contracted by the Department of Health and Environmental Control.
