Environmental Stewardship

Protecting the Environment

We at Schild­berg Con­struc­tion Com­pa­ny, Inc. believe envi­ron­men­tal stew­ard­ship is an impor­tant respon­si­bil­i­ty. Man­ag­ing water qual­i­ty is one of our greater tasks. All of our quar­ries are gov­erned under the Nation­al Pol­lu­tant Dis­charge Elim­i­na­tion Sys­tem (NPDES). Each quar­ry has at least one and some have two NPDES Per­mits. Links to these per­mits can be found below.

Iowa NPDES Per­mit No. 5

Iowa NPDES Per­mit No. 3

Mis­souri NPDES Per­mit MO-G49

At our Iowa facil­i­ties, storm water dis­charge is reg­u­lat­ed by the Iowa Depart­ment of Nat­ur­al Resources NPDES Gen­er­al Per­mit Num­ber. 3. The applic­a­ble Iowa facil­i­ties that dis­charge pump water are also reg­u­lat­ed by the Iowa Depart­ment of Nat­ur­al Resources NPDES Gen­er­al Per­mit Num­ber 5

The Gra­ham Quar­ry in Mis­souri is reg­u­lat­ed under the Mis­souri Depart­ment of Nat­ur­al Resources NPDES MO-G49 permit.

Sites with a stormwa­ter (NPDES) per­mit are required to devel­op, ini­ti­ate and main­tain a Stormwa­ter Pol­lu­tion Pre­ven­tion Plan (SWPPP). All sites reg­u­lat­ed by these per­mits require reg­u­lar storm water inspec­tions to assess the effec­tive­ness of the site’s SWPPP. All reg­u­lar inspec­tions known as Annu­al Com­pre­hen­sive Site Com­pli­ance Eval­u­a­tions” have been com­plet­ed for fis­cal year 2021.
