Maintenance

• In order to effectively control erosion and
  prevent sedimentation, a series of properly
  designed, installed, and MAINTAINED BMPs must be
  utilized

3
Best Management Practices
BMPs Required on LDAs by the Erosion and
Sedimentation Control Act of 1975, as
amended. Three keys to BMPs Proper Design,
Installation, and Maintenance Erosion Control
versus Sediment Control Vegetative
Practices Control Erosion Treat the
Source Structural Practices Control
Sedimentation Treat After Erosion Has Begun
4
The revised 2002 Field Manual For Erosion and
Sediment Control In Georgia specifies the
required maintenance
5
In the Field Manual, each BMP has a section for

• BMP Definition
• BMP Purpose
• Proper Installation
• Proper Maintenance

6
Example from Field Manual

• Construction Exit (Co)
• Definition

7
Example from Field Manual

• Construction Exit (Co)
• Purpose

8

Information found in Maintenance section

• Vegetative Practices Lime requirements,
  fertilizer requirements, re-seeding, mowing, etc.
• Structural Practices Inspections and monitoring,
  clean out and de-mucking requirements, replacing
  materials, etc.

11
The Erosion, Sedimentation and Pollution Control
Plan

• The ESPC plan specifies the location, design
  specifications, installation directions, and
  maintenance requirements for all necessary BMPs
  using GSWCC code.
• Use only the approved plan!

Regardless of recorded readings, this is
not working!!!
Note monitor for water quality

Why maintain BMPs???

• Possible enforcement action by regulatory
  agencies
• Loss of soil and water resources
• Impacts on the environment and economy
• Citizen Complaints
• Civil suits

37
Agencies Involved in Citizen Complaint Resolution

• Local Issuing Authorities
• Local Soil and Water Conservation Districts
• Georgia Soil and Water Conservation Commission
• Environmental Protection Division
• Environmental Protection Agency

Citizen complaints
39
Property Damage

• Adjacent property owners lake impacted due to
  poor installation and maintenance of BMPs.

Summary

• Erosion and sedimentation is a serious problem
  associated with active construction sites.
• Implementing a series of sound Best Management
  Practices that are properly designed, installed,
  and maintained is the only way to prevent
  problems.
• Use the approved erosion and sediment control
  plan and the Field Manual for guidance.
