Q

NPDES

A

Primary mechanism to keep pollution out of waters and meet was’s

  • imposes limitations on discharges
  • state enforces permit
  • Regulates:conventional pollutants (BOD, pH, TSS) non conventional (phosphorous) and toxic (organics and metals)

Q

BMP’s (Six minimum control measures)

A
  • Public education and outreach on storm water impacts
  • public involvement/participation
  • illicit discharge detection and elimination
  • post-constuction storm water management in new development and redevelopment
  • pollution prevention/good housekeeping for municipal operation

Q

Illicit discharge connection

Study These Flashcards
A

this BMP (best management practice) involves identifying and eliminating illegal or inappropriate connections of industrial and business wastewater sources to the storm drain system

23
Q

Pretreatment program

Study These Flashcards
A

3 objectives

  • protect operating POTW’s from upsets
  • Prevent “pass through” of pollutants
  • Improve opportunities for recycling/reclamation
24
Q

POTW’s (Public Owned Treatment Works)

Study These Flashcards
A

Handle domestic, commercial and industrial discharges

  • harmful discharges
  • metals from electro plating and metal finishing
  • organics from pharmaceuticals, petroleum refineries, chemical facilities (cleaning solvents)
25
SPCC (Spill Prevention Control and Countermeasure)
- requirements to prevent discharges of oil to the nations waters - facilities with greater than 42,000 gal buried capacity - not applicable to facilities under DOT - Must include description of facility - type of oil and container - secondary containment- - spill cleanup procedures and cleanup plan - must be amended when change in design - must be reviewed every 5 years
26
SDWA 1974
Goal: to provide safe drinking water to the public - set safe standards of purity for drinking water - require owners of water systems to comply with health-based standards
27
Threats to Drinking water
improper disposal of chemicals - animal wastes - pesticides - human wastes - wasyed injected deep underground - naturally occurring substance - imporper treatment of water - inadequate disinfection
28
Drinking water standards (DWS)
primary and secondary, establishes maximum containment levels (MCL's) - public water supplies bus periodically test and report
29
Underground Injection Control
regulates/restricts/prohibits underground disposal of wastes vis Class I-V system
30
Sole Source Aquifer Protection
extra protection and limited development in designated area
31
Wellhead Protection Program
developed at local level
32
1996 amendment to SDWA
source water protection requirements - operator training requirements - funding for water system improvements - enhancement of public information
33
SDWA rules and regulation
every public water system in the us must comply with this stature -EPA, states, tribes, water systems, and the public work together to implement requirements
34
Public Water Systems
systems that have at least 15 service connections or serve atlas 25 ppl per day for 60 days out of the year
35
Community water system
public water system that serves the same people year round (55,000)
36
Non-transient system
public water system that serves the same people more than 6 months per year but not year round (20,000)
37
Transient water system
public water system that does not serve the same people for more than six months per year
38
Primary Standards
enforceable maximum contaminant levels for particular contaminants in drinking water…treatment required if exceeded. Health based, and enforceable. (protect against health risk, considering available technology and cost).
39
Secondary Standards
Aesthetic, non enforceable | no reporting except for fluoride exceedance
40
SDWA Critical components
-States/water suppliers must assess water supplies - Voluntary adoption of wellhead protection programs - States must certify water system operators and ensure that new water systems have technical financial and managerial capacity to provide safe drinking water. -  Underground Injection Control addresses the injection of wastes into ground water.
41
National Groundwater Policy
sound science and data collection - risk based priorities - community based programs
42
Laws that protect groundwater
SDWA, CWA, RCRA (has waste and UST's), CERCLA, and pollution prevention
43
Subtitle 1 of RCRA(resource conservation and recovery act)
regulated UST's that stope petroleum products and also and substance defined as hazardous under SUPERFUND
44
What are UST's
- any tank that has atlas 10% of its volume buried below ground - includes the piping attached to the tank - can be made of steel, stainless steel or fiberglass reinforced plastic (FRP)
45
UST's that aren't regulated
- farm and residential under 1,100 gallons or less - holding heating oil - tanks on or above the floor of underground areas, basements or tunnels - septic tanks and storm wastewater - tanks of 110 gallons or less capacity - emergency spill and overfill tanks
46
3 Sections of the Federal UST Program
- Technical: prevent releases from spills, overfills or leaking UST's to protect human health and the environment - Financial: correct and clean up leaking UST's - State Program: development of strict state UST programs
47
Leak Detection
- secondary containment with interstitial monitoring - automatic tank gauging - monitoring for vapors in the soil - monitoring for liquids on the groundwater - statistical inventory reconsiliation
48
overfill protection
- catch basins or spill buckets - Automatic shutoff - ball float thing
49
Corrosion Protection
Applies to steel ust's - cathodic protection system - interior lining
50
Reporting and Recordkeeping
- when installing a UST you have to fill out a notification form and submit it to your state or local agency - new installations need a certificate of installation - suspected releases need to be reported to the regulatory authority
51
Corrective action
a recovery well is an example of a way to capture leaking contaminants and removing them from groundwater for treatment
52
More Recordkeeping
- Inventory records - leak detection system testing - corrosion protection system testing - records of any UST repair - records of proper UST closure
53
UST CLosure
- must follow strict guidelines to prevent product from leaking out and contaminating the ground - excavation must be examined and tested for signs of contamination
54
EPA's priorities today(ust)
- using ustfields projects to clean up and potentially revitalize abandoned just sites - improving compliance with just requirements - improving cleanup pace and activities - evaluating ust system performance
