POLICY FOR REDUCED SALT AREAS IN THE
VICINITY OF WATER SUPPLIES
ISSUED
PAGE 1 OF 16
DISTRIBUTION:
Statewide
APPROVED
Signature on
Original
PURPOSE
To establish reduced salt zones for the purpose of minimizing sodium and chloride effects on an industrial or potable
water supply. To clearly identify and delineate the limits of each reduced salt zone in each district, as well as identify the
materials and application rates to be used.
RESPONSIBILITY
The District Highway Director (DHD) is directly responsible for maintaining this policy and ensuring that the procedures
outlined are followed. The operation and maintenance of reduced salt zones requires increased material expenditures
due to the use of calcium chloride and/ or salt-sand mixes, as well as the cost for increased supervision and sand
disposal. All locations shall be closely supervised during all storm events. The District shall be responsible for ensuring
that chemicals for the reduced salt zones are available, and that the maps are distributed in a timely manner to
appropriate personnel including privatized forces for increased awareness.
NOTE: In order to maintain public safety and at the direction of the Chief Engineer or his designee, one or more
applications of straight Salt, Pre-Mix or 50/50 may be applied at 240 lbs. per lane mile.
The Snow & Ice Materials Usage Committee (S&IMUC) shall make recommendations for the addition, deletion or
modification of reduced salt zones. Reduced salt zones shall only be established based on scientific data as required by
SOP, ENV-01-30-1-000. The failure of a municipality or public water supplier to provide the regular monitoring data as
required by the aforementioned SOP to demonstrate the effectiveness of the reduced salt zone may be grounds for
MassHighway to discontinue treating the corresponding section of highway as a reduced salt zone.

DEFINITIONS
Salt or Sodium Chloride is the primary deicer utilized by the Massachusetts Highway Department due to its chemical deicing properties and cost effectiveness;
at 240-320 F. Applied at 240 lbs per lane mile, salt is the most cost effective and best deicer available. It is a crystal that has to become a liquid or brine in order to
work effectively. Salt transforms into brine with the addition of heat, moisture and time.
Pre-wetted Salt is sodium chloride sprayed with Liquid Calcium Chloride 32%. The application rate is 8-10 gallons per ton of salt. Best utilized by spraying on
salt from 300 F and below, and on the first application. The act of pre-wetting serves several functions: it reduces bounce and scatter, and accelerates the salt
going from a solid to solution or brine.
Liquid Calcium Chloride (LCC) 32% is a deicing solution utilized by MassHighway because of its quick melting action. The chemical properties make it ideal for
low temperatures (-600 F) by lowering the effective working range of salt to +/- 100 F. It is Hygroscopic; which means it attracts moisture from the air as well as the
ground, thus making it the perfect deicer to jump start the salt in the creation of a brine. It is used for pre-wetting salt or direct application pre-treatment.
Pre-mix is a combination of Sodium Chloride and Flake Calcium Chloride (Solid). The ratio of the two products is 4:1, 80% Sodium Chloride and 20% Calcium
Chloride. This combination is used in some of the reduced salt zones in combination with sand.
50/50 Mix is a 1:1 mixture of sand with a deicing material. The deicing material may be salt or pre-mix. This material is not the most effective deicer but is used
in reduced salt zones to reduce sodium and chlorides into the environment. This mixture is sometimes used during sleet or freezing rain events.
Liquid Magnesium Chloride 30% a corrosion inhibited deicing agent. A blend of magnesium chloride 30% and an environmentally friendly (Amine) additive
creating a blended chemical 70% less corrosive than conventional deicers. Utilized for Pre-treating of roads or Pre-wetting of sodium chloride. Used now for
evaluation on I-95 North in the Boxford reduced salt zone.

DEFINITIONS CONTINUED
Pre-treatment a proactive strategy designed to prevent a bond between the snow and ice and road surface. This is achieved by the direct application of liquid.
The typical application rate is between 20-30 gallons per lane mile. Pre-treatment is normally done on pavement temperatures of between 15-300F.
Sand: A clean intert, hard material free of organic material with no melting capabilities. Sand is intended to increase friction between vehicles and the pavement.
The sand may be applied “straight,” or it may be mixed with pre-mix on a 1:1 basis. Because of the environmental and economic impact, MassHighway restricts
the use of sand in our operations to reduced salt zones and in extremely cold temperatures.
