DATE: January 3, 2013

SUBJECT:  ENG – National Engineering Handbook (NEH), Part 645, Engineering Technical Materials

Purpose:  To distribute revised and new IL-ENG standard drawings

Expiration Date:  Upon receipt

Explanation: This notice distributes 23 revised and 3 new standard engineering drawings. Major highlights include:

  • New drawings to document design data for waste transfer pumps and agitators
  • Staff gauge for waste storage facilities – new details for embedment of post type gauge to ensure liquid tightness, and an additional type of gauge to use as an alternative to a post
  • Updates to the vertical drain for sinkhole treatment, with guidance on selection of pipe size
  • Adjusted fabric and rock check drawings to allow for widths wider than 2/3 of the grassed waterway top width
  • Lined waterway – change to a limitation on slope rather than overfall, since this is a waterway rather than a grade stabilization structure.

The Illinois NRCS engineering website will be revised to reflect the updated drawings: http://www.il.nrcs.usda.gov/technical/engineer/enggdraw.html.
