Appendix E: Explanation of the State Clearinghouse Number

The State Clearinghouse Number (SCH #) is a ten-digit number which is unique to each project reviewed through the State Clearinghouse. The sequencing of the numbers has evolved through the years. As of January 1, 2000, a new sequencing went into effect. The first four digits indicate the year in which the document was processed by the State Clearinghouse (or first processed in the case of projects that circulate through the State Clearinghouse several times). The next two digits indicate the month in which the document was processed. The next digit indicates the geographic location of the project (i.e. "region"). The last three digits indicate the sequence in which the document was processed for that month.

Example: 2000053089 -- The document having this SCH number was the eighty-ninth document processed in May of 2000 for Region #3.

The same State Clearinghouse number must be used on all documents relating to a particular project. This enables the Clearinghouse to keep better records of projects and assures that comments and subsequent documents will be correctly filed for future reference.

Please Note: The new sequencing required changing the SCH # from an 8-digit to 10-digit format. Please be advised that all documents received prior to January 1, 2000 will now have a "19" preceding the existing SCH #. We request that you add these two digits to the SCH # of any documents you forward to us that were numbered in the 8-digit format. For example, a project from 1999 would have an SCH # of 1999122001. Additionally, all new environmental documents will be assigned a 10-digit number (i.e. beginning with "2000").

IMPORTANT: Always identify any known SCH number on all communication with the State Clearinghouse. It is especially important to reference the SCH number on environmental documents that have previously been circulated by the Clearinghouse, as the staff can use these numbers for cross-reference.
