Limit Sets

1. Limit Sets

2. Limit Sets Defined • Limit Sets - groups monitoring & reporting requirements for each Permitted Feature • Limit Sets typically apply during particular operating conditions such as: • Summer vs Winter • High production volume vs low production volume • Frequency of reporting (monthly, quarterly, yearly, etc) • Limit Sets define Discharge Monitoring Reports (DMRs) • What date range will be covered on the DMR form • When the first DMR will begin • when the DMRs are due to the Agency

3. Limit Set Example • 001 has monthly, quarterly, and yearly requirements • Create 3 Limit Sets - For Expected DMRs and Generation of Violations Jan Feb Mar Apr May Jun Jul Aug Sept Oct Nov Dec X X X X X X X X X X X X Monthly X X X X Quarterly X Yearly

4. Actual Permit Language • General Foods, Permitted Feature 001

5. Types of Limit Sets • There are two types of Limit Sets • Traditionally, Limit Sets are Scheduled • DMRs are expected on a predictable basis • Non-Receipt Violations are generated when 30 days late

6. Unscheduled Limit Sets • Special Regulatory Programs may need Unscheduled Limit Sets • DMRs are entered on an as-received basis • There is no DMR Due Date • DMR Non-Receipt Violations are never generated • Unschedule Limit Sets support the variable reporting needs of the Storm Water, Biosolids, and other programs • Appropriate for event-based reporting, rather than a continuous discharge

7. Comparison Chart

8. Expected DMRs • Using Limit Set (and Limit) data, ICIS-NPDES creates an Expected DMR Schedule • Allows users to see the expected discharge activity • Aids in validation of submitted DMR data • Scheduled Limit Sets get an Expected DMR Schedule when at least one Limit has been added to the Limit Set • Expected DMRs are created one-at-a-time as they are received for Unscheduled Limit Sets • The Expected DMR Schedule will be discussed more during the Limits and DMR units

9. Limit Set Decision Making • General Foods Permit • Should we set up limit sets for “Scheduled” or “Unscheduled” Limit Sets? • Do you know how often they should sample (monthly, quarterly? • Both – monthly and quarterly • are the DMRs due on a specific date? (check permit) • Yes. “no later than the 15th of the following month” • Scheduled or Unscheduled? • Scheduled

10. Example of Report Units • Example of an actual permit with different reporting frequencies

11. Limit Set Data Entry

12. Limit Set Screen • The Limit Set Screen captures the following information • Limit Set Information • Limit Set Designator • Default Months Limit Set Applies • Status information • Schedule information • DMR Pre-print information • User Defined Fields • Default Statistical Base Codes

13. Accessing Limit Sets from Permitted Feature • From the Permitted Feature hyperlink • Limit Sets

14. Accessing from Limit Set Hyperlink • From the Limit Set hyperlink

15. Fields Required to be Entered • Permitted Feature will have to be manually entered

16. Limit Set Unique Data Elements • Individual Limit Sets are unique according to the following data elements • NPDES ID • Permitted Feature Identifier • Limit Set Designator (can be 1-2 characters, alphanumeric) • Users are also able to name Limit Sets; the Limit Set Name is pre-printed on DMRs

17. Default Months • The default is “all months” checked • The months checked on the Limit sets do not have to match the individual parameter limits • Essentially the seasons on the parameter limits will override the ones on the limit set

18. Default Months Seasonal • Seasonal limits (i.e. Winter/Summer) • As a data entry convenience, users may select default months that the Limit Set applies • When coding the parameter limits the months selected below will be the default for each parameter limit • Edits to Limit Set Months do not trickle down to already existing Limit Months

19. Limit Set and Compliance Tracking Status • Limit Set Status gives users the ability to turn a Limit Set on or off for violation generation for a period of time • Active (default) • Inactive • Like Compliance Tracking Status on the Permit, users can enter multiple Limit Set Statuses

20. Schedule Data Fields • Schedule Data include • Number of Report Units • Number of Submission Units • Initial Monitoring Date • Initial DMR Due Date • Modification Effective Date • Modification Type

21. Schedule Data Fields • Schedule Data define the monitoring and reporting requirements for a Limit Set • These fields are very important in ensuring that violations are generated accuracy and DMRs are for the correct timeframes • Invalid non-receipt violations

22. General Foods Example

23. Actual Permit Example • Let’s enter our Limit Sets for General Foods 001 A Monthly 001 Q Quarterly

24. Number of Report Units • Number of Report Units • The number of months covered by the DMR form (e.g., Number of Report Units = 3 reflects quarterly, 3-month long DMRs) • Always measured in months • General Foods Permit 001 A – what is the # of Report Units? 1

25. Number of Submission Units • Number of Submission Units • The number of months DMR are submitted (e.g., Submission Units = 6 means submit DMR(s) every 6 months, = 3 means submit DMR(s) every 3 months • Must be greater than or equal to Number of Report Units • Must be evenly divisible by the Number of Report Units • General Foods Permit – What is the submission units? 1 1

26. Initial Monitoring Date • Initial Monitoring Date • The date at which monitoring begins for the Limit Set • Always begin on the 1° day of the month 1 1 07/01/2012

27. Initial Monitoring Date • Initial DMR Due Date • The date that the first DMR for the Limit Set is due to the regulatory authority • Must be greater than or equal to the Initial Monitoring Date + the Number of Submission Units • For example, if a DMR starts monitoring on June 1st, and Number of Submission Units = 2, the Initial DMR Due Date must be greater than or equal to August 1st 1 1 07/01/2012

28. Initial Monitoring Date • General Foods Initial DMR Due Date? When is the July 2012 DMR due to your Agency? 1 1 07/01/2012 08/15/2012

29. Initial Monitoring Date • Initial Monitoring Date (IMD) can occur before the Permit Effective Date of the permit • Business Rule - first DMR end date must be on or after the effective date of the permit • Examples for Permit Effective Date of Sept 1, 2013 Monthly DMRs start 9/1/13 (IMD = 9/1/13) Quarterly DMRs for period July – Sept (IMD = 7/1/13 or 10/1/13) Semi-Annual DMRs for July – Dec (IMD = 7/1/13 or 01/01/14) • Yearly DMR for Jan thru Dec (IMD = 1/1/2013 or1/1/2014)

30. Modification Fields • Original permit contains a change to the limits during the life of the permit • Referred to as modified limits • i.e. when construction is completed and plant expanded, limits will be modified to meet the new conditions • Modified permit can be issued • Original eff 7/1/2012 exp 6/30/2017 • Modified eff 4/1/2014 exp 6/30/2017

31. Agency Reviewer and Comment Fields • Data entered in this section will be pre-printed on all the Limit Set’s DMRs • Users can identify • Agency Reviewer • DMR Comments

32. User Defined Fields • User Defined Fields • Optional fields that are available for states and regions to use at their own discretion

44. Other Limit Set Tidbits

45. Expected DMRs and Violations • These data drive the Expected DMR Schedule and calculations of DMR Non-Receipt Violations • Updates to these data will have ripple effects in the system • If an update will lead to the orphaning of received DMR data, the system will not allow the update • For example, a monthly Limit Set cannot be changed to bimonthly if DMR data have been received for an off month • Delete the “orphaned” DMR data first before making the Limit Set change

46. Change in the Limit Sets Exercise Date Orphaned Yes/No Nov. 2013 Y / N Feb 2014 Y / N Mar 2014 Y / N Aug 2014 Y / N Sept 2014 Y / N

47. Change in the Limit Sets Exercise - Answers Date Orphaned Yes/No Nov. 2012 Y / N Feb 2013 Y / N Mar 2013 Y / N Aug 2014 Y / N Sept 2014 Y / N

48. Statistical Base Codes • As a data entry convenience, users may select default Statistical Base Codes (stat base codes) that will be applied to all Parameter Limits • Recommend that you only use this when you have a large number of parameters with the same stat base codes • Limit Statistical Base Codes do not have to match the Limit Set defaults • Edits to Limit Set Statistical Base Codes do not trickle down to already added Limits

49. Statistical Base Codes • Using the default Stat Base code may cause data invalid non-receipt violations if you don’t check your permit requirements carefully

50. Statistical Base Codes Maximum Minimum
