Re: Great Western Chemical Company Project

Springfield, OP.97477
Dear Mr. Puent:
As "Engineer of Record" on the above referenced project, I would like to request that
you allow Ordell Construction Company to add the roof insulation and sheeting to the building
purlins to add the additional diaphragm support to the roof system. I am concerned that the
spaced purlins with x-bracing rods in place will not be adequate to safely insure the building
systems integrity.
If you can see your way clear to allow the work to proceed through the sheeting stage it
would be greatly appreciated and allow me to sleep better nights. Thank you.

l. Land alteration has occurred on this site prior to obtaining a valid Land and Drainage Alteration Permit.
2. No wetlands identified
3. The plans as submitted show minimal erosion control measures and no construction staging. The plans as submitted
are inadequate in that they fail to show the minimum application requirements even after several communications to
the Engineer/owner. The geology report submitted is for seismic evaluation and not appropriate for this permit
application. It should be re-directed to the building plan review application.
4. Site and City Storm System drains into identified wetlands.
Conditions
This document is an extension to the conditions of the Land and Drainage Alteration Permit. These conditions must be
carried out in addition to and as a part of any other conditions or requirements listed on this permit application and shall
be in addition to any current or pending permit application(s) or land use decisions. The owner shall be required to be in
compliance with federal, state and local ordinances and codes, and sound engineering practices with regard to activity on
this site. Specific conditions shall include but not be limited to the following;
l. Wet weather conditions are now in effect through April 30, and may be extended if wet weather exists beyond that
date.
2. Sediment from the consffuction must be trapped and prevented from leaving the project site or entering streams,
drainage ways, wetlands, or other environmentally sensitive areas. Private and public property down gradient of the
project site shall be protected against erosion during construction caused by runoff from the Project site. Runoff from
the project site during construction shall be protected so that sediment-laden water will be filtered before entering the
conveyance system.
3. Temporary erosion control facilities must be designed for the 2-year,24-hour storm.
4. Stabilization of all exposed areas will be required within 48 hours after reaching finished grade.
5. Sediment and erosion control measures shall be in place and functioning before clearing and grading begins.
6. Construction site entrances are egress points for vehicles onto paved public roadways. All projects, which will have
vehicular traffic, shall have an approved means to prevent vehicles from tracking soil from the site. The owner shall
maintain the entrance(s) as necessary to ensure proper functioning of the system. The inspector may require
stabilization of interior roadways and car parks to keep sediment contained.
If sediment is tracked offsite, sediment shall, on a daily basis, be swept or shoveled from the paved surface before
washing.
Runoff from construction entrances shall be directed to sediment ponds or traps where these have been otherwise
provided on development sites.
7. Erosion control facilities shall not be allowed to fall into disrepair. The owner shall inspect facilities during and after
rainfall events to ensure that they continue to function effectively. Repairs shall be made as soon as possible during
rainfall events.
8. Temporary erosion control measures may not be removed until the site is permanently restored to the satisfaction of
the inspector. For projects that contain or adjoin drainage ways or environmentally sensitive areas, or occur on slopes
over l5 percent, the Director may require a restoration plan that shall consider vegetation types, mulching/armoring,
and/or maintenance to affect the following:
o Erosion and sediment control
o Soil and slope stability
o Protection of drainage ways and environmentally sensitive areas.
9. All temporary erosion control measures shall be removed within 30 days after final site stabilization has been
achieved or after the measures are no longer needed. Sediment collected in traps, ponds, or silt fence shall be
removed and disposed in an approved manner or stabilized on site. Disturbed soil areas resulting from sediment
removal shall be permanently stabilized within seven days.
10. Straw bale barriers are temporary and have a life expectancy of two months or less. The purpose of straw/hay bale
barriers is to l) intercept and detain small amounts of sediment from disturbed areas of limited extent in order to
prevent sediment from leaving the site, and 2) decrease the velocity of sheet flows and low level channel flows
o Straw/hay bale barriers are not a substitute for filter fabric fences as they are short-lived and provide very
little filtration of sediment. Straw and hay bales may be used below areas subject to sheet and fill erosion. The
size ofthe drainage area is to be no greater than 0.25 acre and the length ofthe slope behind the barrier
should be no greater than 100 feet. Ifthe slope has a gradient greater than l0 percent, slope length should be
no more than 50 feet.]
o There shall be no concentration of water or possibility of a washout in a channel above the barrier.
I l. Ifdrainage problems to adjacent properties are caused by or as a result ofactivity on this site then the
applicanVowner/developer will be required to place additional storm drainage to remedy the situation.
12. The owner/contractor shall maintain adequate erosion control measures at all times. Failure of the owner and or
contractor to provide adequate erosion control measures even if not shown on the plan or documents shall constitute
a violation of this permit and the owner and or contractor shall bear full liability.
13. Payment of additional fees in the amount of $1207.09 for additional staff time beyond the normal permitting process
must be paid at the time of or prior to issuance.
14. Issuance of this permit shall be conditional upon the engineer of record providing the City of Springfield with a Ietter
stating that the work done to date meets minimum Federal, State and local codes and conforms to the requirements of
this permit.
15. Failure by the owner and./or his contractors to follow and adhere to these conditions, permit requirements, City of
Springfield ordinances, State and Federal codes and laws in part or in the whole may result in stop work orders,
revocation of permits, fines and penalties, attorneys fees, court costs and costs associated with cleanup and
restoration to the site, public right of ways, public and private drainageways and drainage systems, wetlands and
private property.
