The coding schemes presented in this appendix were
identified during the review.of the 15 representative systems
as part of the quantitative analysis of the need for a data
management and standardization program. Three types of
information is presented for each identified coding scheme.
They are:
Code Ho. - The Code Number is a project team assigned
number used to identify the specific coding scheme.
The numbers have an alphabetic prefix to identify the
coding scheme category and a sequentially assign
number. The code number is used in the Data
Dictionary in Appendix A to reference the specific
coding scheme used for that data element.
Field - Information is provided in this column when
specific information about the data element is provided
by specific character locations in the coding scheme.
For example, the. first two characters in a location
code may identify the state and the last three
characters, the county.
e_ - This column contains the name and/or description
the specific coding scheme.

limited ("E") or Water Quality Limited ("W"). This
data element should be entered for all WWT
facilities including those which utilize land
application techniques for treated effluent.
Legitimate entries are:
Positions 1-2 - "00" - "99"
Positions 3-4 - "00" - "99"
