• Standard Monitoring Plan (SM)
• System Specific Study (SSS)

7
IDSE Implementation Timeline
Schedule for systems in a combined distribution
system is based on that of the largest system in
the combined distribution system
8
Very Small System (VSS) Waiver
9
Eligibility Criteria

• Systems must
• Serve fewer than 500 people
• Have taken TTHM and HAA5 samples
• Reduced monitoring acceptable
• Operational data acceptable
• 137 systems out of an eligible 243 systems in
  South Dakota have received their VSS Waiver

Note EPA or the state may deny a VSS Waiver for
any reason, even if system meets all eligibility
criteria
10
VSS Waivers

• Waivers effective immediately
• No application necessary
• Systems must meet all criteria
• EPA or the state can require Standard Monitoring
  or System Specific Study
• VSS Waiver is only a waiver from additional IDSE
  activities
• No Standard Monitoring or System Specific Study
  Plan
• No IDSE Report
• Continue compliance with Stage 1 DBPR until Stage
  2 DBPR compliance begins
• Complete a monitoring plan for the Stage 2 DBPR

11
40/30 Certification
12
Eligibility Criteria

• Systems must have Stage 1 DBPR data or data
  equivalent to eight quarters worth of sampling
• No individual sample can have exceeded
• 0.040 mg/L for TTHM
• 0.030 mg/L for HAA5
• No TTHM or HAA5 monitoring violations
• For schedule 3 and 4 systems data can not be
  before January 1, 2005
• Approximately 88 systems in South Dakota will be
  eligible for a 40/30 Certification

Note EPA or the state may deny the certification
for any reason, even if system meets all
eligibility criteria
13
Operational Data

• EPA or the state may allow systems to use
  operational data to qualify for 40/30
  certification.
• Data must be equivalent to Stage 1 DBPR data.
• Samples must be taken and analyzed by approved
  methods at a certified lab.
• Adequate number of sample sites for system size.
• Samples must be taken at appropriate locations
  (average or maximum residence times).
• Samples must be taken at appropriate frequency
  and during the month of warmest water
  temperature.

14
Submitting a 40/30 Letter

• Once a system has collected a sufficient amount
  of data it can prepare a 40/30 Certification
  Letter and submit it to the EPA
• Electronically (through EPAs DCTS)
• Hard-copy (through mail)
• US EPA-IPMC PO Box 98
  Dayton, OH 45401-0098

• Certification
• I hereby certify that each individual Stage 1
  DBPR compliance sample collected from ________ to
  _______ was less than or equal to 0.040 mg/L for
  TTHM and 0.030 mg/L for HAA5. I understand that
  to be eligible, each individual sample must be
  equal to or below these values. I also certify
  that this PWS collected all required Stage 1
  samples and did not have any monitoring
  violations during this time period.

Standard Monitoring
17
Standard Monitoring Requirements

• Population served
• Source water type
• Justification of Standard Monitoring sites
• Distribution system schematic
• Entry points, sources, and storage facilities
• Locations and dates of proposed Standard
  Monitoring sites
• Locations and dates of Stage 1 DBPR monitoring
  sites

18
Standard Monitoring Requirements

• What, where, and how often do I monitor?
• Samples Collected
• Dual sample set (both TTHM and HAA5) collected at
  all locations
• Monitoring Locations
• High TTHM levels
• High HAA5 levels
• Average Residence Time
• Near Entry Points
• Number of sites
• Based on systems source water type and
  population served
• Monitoring Frequency
• 1, 4, or 6 monitoring periods during the year at
  each location
• Number based on population served and source type

19
TTHM and HAA5 Standard Monitoring(1)

• For groundwater systems or systems that purchase
  groundwater

(1) A dual sample set (i.e., a TTHM and an HAA5
sample) must be taken at each monitoring location
during each monitoring period. (2) The peak
historical month is the month with the highest
TTHM or HAA5 levels or warmest water temperature.
20
TTHM and HAA5 Standard Monitoring(1)

• For Subpart H systems and systems that purchase
  Subpart H water

21
Standard Monitoring Site Selection
Justification

• Plan must include a justification for the
  selection of sites to be sampled during Standard
  Monitoring
• Data sources and tools
• Distribution system maps
• Water quality data
• Distribution system operating data

22
Final Selected Sites

• Some site selection will be obvious
• Near entry point
• Others will require professional judgment
• Consider geographic representation
• Consider hydraulic representation
• Consider areas fed by sources with higher DBP
  precursors
• Consider accessibility

23
Submitting Standard Monitoring Plan

• Once the system has collected and analyzed its
  information, it must prepare the plan and submit
  it to EPA.
• Electronically (through EPAs DCTS )
• Hard-copy (mail to IPMC address)
• Must include required information
