Correction to Septic Loading Rate Chart - Column 5E has been corrected from 0.52 g/d/sq.ft. to 0.69 g/d/sq.ft. This has historically been the established rate, but an error had been made in the printing of the table. Use this corrected table for Section 905A, Appendix A, Illustration M, Exhibit B - Key for Determining Sewage Subsurface Loading Rates for Illinois Soils - in the State of Illinois Code for Private Sewage Disposal. The table that is in the Code itself, has many errors and is a corrupted table.
