Item 23 - If the facility generates domestic wastewater from stoke, toiled and/or showers, please complete this item. Indicate the source(s) of such wastewater,
what treatment is provided and what method of disposal is utilized (surface discharge, Icach field, etc.). Also, if sludge or other solid waste is generated
fiom these activities - describe the source(s), how often i[ is disposed o~ the ultimate disposal site and any other pertinent information.
Items 24, 25, 27 - Selfexplanatory.
Item 26, 28 These items require monitoring for various pollutand. With the excepfion of item 26 all analyses should be done only at
and 29 - outfalls that are not solely made up of storrnwater and domestic wastewater. In item 26, analysis for the indicated parameters shall be performed on
each outfafl and receiving waters immediately upstream of the outfafl. If more than one oulfali is to a common body of water, only one analy~s of the
receiving water upstream of the upper-most outfall will be required. If the receiving stream is dry during portions of the year, so indicate. In the case of
sedimentation ponds for smmrwater runoff, one ou[fall can be sampled if it can reasonably be assumed to be represenhstive of all sedimrndtion pond
outfalls.
For item 28, the WET testing shalt be conducted on 100% e&]urnt and be for both Ceriodaohnia dubia and fathead mivvows. This regrmement is
waived where routine testing is currently required. The test shall be an acute test unless the ratio of stream low flow to effluent design flow is less than
10:1, respectively, and the receiving stream has a Class 1 Aquatic Life Use or Class 2 Aquatic Life Use will all the appropriate aquatic life numeric
standards. In the latter case a chronic test is required. The Division reserves the right to request additional WET testing es part of the application
review. If so requved, the permit will not be processed until the additional information is submitted. WET testing procedures are described in the
Guidelines for Conducting Whole Effluent Totdcity Tesd. which can be obtained from the Division. Fot item 29, a priority poiludrrt scan is required
unless the probable total annual production is less than 100,000 tons pa year. The paameters for the appropriate GC/MS fraction(s) are shown in
Appendix A.
For all three items, effluent samples and all insfream samples can be grab samples. Include the sampling date and the name of the laboratory
perfomting the analyses. Whrn quantitative data for a pollutant are required, the applicant must collect a sample of effiurnt and analyze it for the
poluant m accordance with analytical methods approved under 40 CFR Part 136. When no amalytical method is approved the applicant may use any
suitable method but must provide a dcscriptiw of the method. The Division may allow or esdbhsh appropriate sito-spceific sampling procedures or
requvemrnd, including sampling locations, the season in which the sampling takes place, protocols for collecting samples and additional time for
submitting data on a caso-by-case basis.
1T IS RECOMMENDED THAT YOU CONTACT AN ANALYT[CAL LABORATORY PRIOR TO SAMPLING AND ANALYSIS
SO THAT PROPER PROCEDURES ARE FOLLOWED.
If this is an application for renewal, reduced sampling maybe appropriate, wntact the Pertnid Unit at [phone]. H there is mo efllaeat and/or
receiving water to analyze, indicate this.
Item 30 - The applicant must reviewAppendices Aand Band must indicate whether it knows or has reason to believe that any oflhe pollutants listed are present
in the discharge. The Division nmy waive the reporting requvemrnd for individual point sources if the applicant has demonstrated that such a waives
is appropriate because information adequate to support iasuertce of a permit can be obtained with less stringent requiremend. Each applicant must
report quantitative data for each outfall containing process wastewater with the following exceptions:
a) For every polludrtt discharged which is not so limited m an effluent lindmdons guidelinq the applicant must either report quantiative dam or
briefly describe the reasons the pollutant is expected to be discharged.
b) For every poflutam exported to be discharged in concentrations of 10 mg/P or greats the applicant must report quantitative data. For acrolein,
acryionitrilq 2,4 dinitrophenol, and 2-methyl-4,6 dinitrophenol, where any of these four pollutand are expected to be discharged im concentrations
of 100 Q}g/P or greats the applicant must report qualitative data. For every poflumnt expected to be discharged in concentrations less than ]0
dyg/P, or N the case of acrolein, acrylonitrile, 2,4 dinitrophrnol, and 2-methyl-0,6 dinitrophrnol, in concentrations less than 100 mg/P, the
applicant must either submit quantitative dam or briefly describe the reasons the pollutant is expected to be discharged.
c) The applicant need not provide quantitative date if the pollutant is present in the discharge solely as the resuh of its presence in intake water.
I-Ioweva, the applicant must repot such polluant as present.
Item 31 - Please submit a copy of summaries of ell water quality dam performed in the previous five years under conditions of the permit from the Colorado
Division of Minerals end Geology. Such monitoring is often submitted a9 part of the annual report to CDMG and may consist of both oulfefl sampling
and instream sampling. If such monitoring is not required, Please so sdte.
Item 323 - Self Explanatory.
Item 34 - Describe those measures taken to control pollutand from entering wastewater streams. Do not include items which are detailed in the facility's
Stonmvata Management Plan.
Item 35 j6 - Self explanatory
Item 37 - Udess abeady covered by a s[ormwater permit, all apphcand must complete the stomrwata application form included erg Apprndix C-1. No other
fore is necessary. Questions relating to Appendices C-1 and C-2 should be directed to the atormwater group at [phone]. PERMrITEES
