Policy Making and Implementation


The Environmental Protection Agency at the
federal and state level are greatly involved in
making policies.


Types of policy used in examples:


Regulations


Found in the Ohio Revised Code


EPA Policy


Interpretation of federal law for use by EPA employees


For use as guidelines

8

Policy Implementation


Ohio Revised Code Regulations


These regulations are implemented by state law.


These laws are then enforced by both the EPA and
general state law enforcement.


EPA Policy


Water Quality Policies


Do not have the power of law.


For use as guidelines.


Operational Systems Policy


Implemented by federal or state law.


Implemented via interoffice exchange.


9

How and Why?


EPA Water Quality Policies


Guidelines for standardized testing for
contaminates in the water


Ensures equal testing parameters statewide


Do not have the force of law


Guidelines for how to test for and track contaminates.


Precursor to a law or regulation


How and Why?

10

How and Why?



EPA Operating Systems Policy


Policies put together so that federal or state law
can be implemented.


These serve as instructions for EPA employees to
ensure that they are keeping records of data in the
appropriate manner.


Ensure that the state remains under compliance with
federal or state law.

11

How and Why?


Ohio Revised Code Regulations


Federal and state congresses pass a law and then
ask EPA for a policy so that the law can be
implemented.


EPA is a regulatory agency that creates a policy or
regulation that has authority based upon a law
that has been passed by congress.

World Information Transfer


Discussed combating water contamination in
rural African villages and at their
19
th

conference in 2010


nonprofit organization non
-
governmental
organization that promotes environmental
health and literacy


foster education and provide aid to schools,
hospitals and orphanages in environmentally
devastated areas

13

Water Innovations Alliance


Promote accelerated development adoption
of water technologies and methodologies


Held a conference @ UD for the first time in
2010


focused on developing new funding, reducing
regulatory barriers, increasing collaboration
and raising awareness for cutting
-
edge water
technologies and the problems they
solve

14

National Water Research Institute


focuses on ensuring safe and reliable water
sources


funds and supports research studies, water
-
related educational programs, and holds
workshops on new water technologies


Uses support of other leading organizations in
water industries and private
foundations

Dayton, Ohio


16

Dayton Water Treatment


Water is supplied by wells in the Miami and Mad
River Well Fields


Ottawa Water Treatment Plant and


Miami Water Treatment Plant


Each plant has a rated capacity of 96 million
gallons per day


Lime (calcium oxide), fluoride and chlorine are
used for water treatment


final step in the treatment process: Rapid sand
filtration


17

Cincinnati, Ohio


Greater Cincinnati Water Works (GCWW)

18

Greater Cincinnati Water Works
(GCWW)


Has been nationally recognized for it’s
excellent drinking water


Most GCWW consumers receive water from
the Miller plant


Miller plant uses Granular Activated Carbon
(GAC) treatment


Allows for substantially less chlorine in the
treatment process


19

Granular Activated Carbon Treatment



best way to remove organic materials from
water


After settling and filtration, water at the Miller
Plant is filtered through beds of GAC


Millions of pores in GAC capture (or "adsorb")
the organic substances


Most spills in the Ohio River are organics


20

Water Quality Issues in Ohio



Environmental Protection Agency’s
investigation of Clyde, Ohio


Cancer among children


Research results


Inconclusive as to what caused cancer


High levels of iron, sulfate and dissolved substances
were naturally occurring in the aquifer

21

Is Current Water Treatment Policy
Effective?
