A.
Most highway agencies and municipalities
are responsible for the cleaning and maintenance of roadways, highways,
and parking facilities under their maintenance purview. Activities
include, but may not be limited to, street sweeping, flushing, applying
surface seals, patching, snow removal, and emergency response to spills
and accidents.
B.
Street sweeping operations normally involve
self-contained and powered collection devices, utilizing belt conveyors
or vacuum systems. This work may be performed on a scheduled basis,
or when requested, and is usually conducted on roads with curbs where
debris can accumulate in the gutter line.
C.
Many agencies flush bridge decks and parking
structures in the spring to remove de-icing chemicals and to clean
the drainage structures. Also, flushing operations are performed on
sections of pavement where mud or debris accumulates after flooding,
creating hazardous conditions.
D.
Bridge decks and parking structures are
normally sealed on a five- to seven-year cycle to protect the concrete
and steel reinforcement from corrosive elements.
E.
Patching operations involve the preparation
of potholes and the fill of either hot mix or cold patching material.
F.
Highway agencies plow and salt the roadways
under their maintenance jurisdiction during winter snow events. Typically,
two hundred (200) to four hundred (400) pounds of salt per lane mile
is used to de-ice the pavement. Other chemicals, such as calcium chloride,
are used when prevailing temperatures fall below twenty degrees Fahrenheit
(20° F.).
G.
Most highway agencies are required to respond
to emergency situations involving spills and debris from vehicles.
This work is performed if it is determined that the material which
will be removed from the public road right-of-way is of a non-hazardous
nature. Hazardous material is handled through hazardous material removal
procedures not specified in this Article.

A.
All City of St. Ann maintained road networks,
bridges and City-owned parking lots.
B.
The Public Services Department provides
for street and sidewalk maintenance, snow and ice removal from streets
and bridges, cleaning of streets and right-of-way and maintenance
and repair of City-owned parking lots and drives.
[R.O. 1998 § 550.380; Ord. No. 2802 §1, 7-17-2012]
The responsible parties involved
in the cleaning and maintenance of streets and parking lots include:
Public Services Director —
314-447-1650
Street Superintendent — 314-428-6802
[R.O. 1998 § 550.390; Ord. No. 2802 §1, 7-17-2012]
Large quantities of materials are
expended in the performance of work. Some material is purchased and
used immediately, while other material is stockpiled. Agencies working
within the constraints of their budget weigh fiscal responsibility
against the immediate and long-range needs for such materials, and
adjust their purchasing habits accordingly.

A certain amount of construction
spoil and waste is generated during the performance of maintenance
operations on our road network. Recycling methods are employed if
they are determined to be cost-effective; however, in many instances,
waste material must be removed from the work site by various disposal
methods.

First preference is to recycle the

or in asphaltic concrete, etc. If material can't be economically recycled,
it will be disposed of in a landfill.

A.
Maintenance.
1.
If certain road maintenance activities
are prone to produce pollutants that can be carried off with stormwater
runoff, schedule these maintenance activities during times of dry
weather if possible.
2.
Capture scrapings/rust/dirt/sandblasting
grit/over spray/drips, etc., from preparation and painting of bridges/structures/traffic
control devices.
3.
For steel girders on bridges, utilize
certified inspectors to inspect for lead-based paint on structures
older than 1978. Use only State-certified removal contractors for
lead-based paint abatement.
4.
Used asphalt is recycled when it
is cost-beneficial.
5.
Block scuppers and drains when sealing
bridge decks.
6.
On asphalt overlays, ensure stormwater
drainage capacity of curbs and inlets is maintained by milling down
into the street at the curb, or using open-graded thin-bonded overlay.
7.
Comply with St. Louis County or municipal
land disturbance ordinances and programs implemented under the St.
Louis County Phase II Stormwater Management Plan. For projects less
than the land disturbance program thresholds, employ BMPs for erosion
and sediment control.
8.
All construction or maintenance activities
that excavate in or discharge any dredge or fill material into a "water
of the United States," which includes ditches, creeks, rivers, lakes,
ponds and wetlands, requires a Corps of Engineers 404 permit and a
MDNR 401 water quality certification. Examples of construction or
repair activities requiring a permit include: bridge work, culverts
under road crossings, dredging or placing riprap in creeks. See Appendix
5-F1[1] for a summary of permit requirements.
[1]
Editor's Note: Appendix 5-F1 is included as an attachment
to this Code.
B.
De-Icing.
1.
Use calibrated chemical applicators
for salt and brine applications.
2.
Minimize the use of salt without
compromising public safety.
3.
Stop salt feed on trucks at stop
signs, where equipped.
4.
Stored salt is on an impervious surface
and is covered.
5.
As available, use road weather information
such as weather forecasts, meteorological data, and pavement sensors
to maximize the efficiency and effectiveness of resources.
C.
Cleaning.
1.
Remove as much mud, grit, salt and
debris as possible (by scraping, brooming, etc.) prior to roadway
flushing on bridges.
2.
Evaluate the need for street sweeping
to remove grit and trash at facility parking lots and roadways within
jurisdiction. Implement street sweeping, when feasible, focusing on
heavy traffic patterns, seasonal variations (spring/fall), and problem
areas. Record the volume of trash/debris removed to identify the priority
of areas being cleaned and the effectiveness of resources used. Investigate
to determine sources of litter in areas of excessive accumulation.
3.
The environmentally preferred sweepers are those with an integral collection device and fugitive dust control. Properly dispose of trash/debris as indicated in Section 550.400 above.
4.
Do not hose down parking lots in
a manner that discharges wash water to the storm drain untreated.
[R.O. 1998 § 550.420; Ord. No. 2802 §1, 7-17-2012]
Employees involved in street and
highway maintenance and repair will be trained on the BMPs in this
Article.
