(d) The clerk of the proper court shall provide a suitable well-bound book, at the expense of the county or city, to be called the environmental service lien docket, in which the notices of liens shall be recorded and indexed. The clerk may not collect more than $2 for recording and indexing each lien or release of any lien.
