BEST MANAGEMENT PRACTICES FOR

CEMENT PLANTS AND ROCKMINING FACILITIES

     

Best management practices can be thought of as using "good housekeeping"

practices.  Listed below are several procedures to operate your facility

and minimize the risk of contamination to the environment.

   

For facilities performing vehicle maintenance:

     

1.    A waste oil and waste fluid collection area must be set up.  This

            area must have a bermed impervious surface and be under cover.

            Wastes are to be stored in clearly marked containers that are in

            good condition.  Leaking containers must be replaced.  Strippers,

            chlorinated solvents and flammable solvents must be kept

            separately.

 

      a.   Waste oil is to be disposed of by a permitted waste oil

                  hauler.  Receipts must be obtained and kept at your facility.

        

      b.   Chlorinated solvents, strippers or flammable solvents must be

                  recycled by a permitted solvent recycler or disposed of as

                  hazardous waste.  This waste must be shipped by a permitted

                  hazardous waste hauler to an approved EPA facility.  Receipts

                  and/or manifests must be kept at your facility, available for

                  review.

           

      c.   Antifreeze must be collected and shipped by an approved

                  hauler ir rectcked ysubg a certified recycling unit.

                  Receipts must be kept at your facility, available for review.

         

2.   All used parts with oil or grease must also be stored on an

            impervious surface.  All excess oil and grease should be removed

            before storage.

 

3.   Used oil filters must be collected and handled by a permitted

            hauler or recycler.  These filters can not be disposed of in the

            trash as solid waste.  A list of oil filter recyclers is available

            upon request.

   

4.   Rags used during mechanical repairs or cleaning processes which

            become contaminated with waste oil or solvents are considered

            hazardous wastes and may be handled by an approved rag service or

            an approved hazardous waste transporter.

     

5.   Steam cleaning, pressure cleaning, truck washing and/or parts

            washing may not be done over open ground.

 

      a.   Parts washing must be done in a container or a parts washer.

                  The parts can be rinsed or air dried over the parts cleaning

                  container.  Absolutely no fluid, not even rinse water, is to

                  be disposed of to open ground, storm drains or septic tank.

                  Research has shown that this rinse water contains solvents,

                  metals, oil and grease.  Dirty parts washing fluid may be

                  recycled or disposed of properly as previously discussed

                  above in 1(b).  A permitted parts washing contractor who

                  brings new fluid and takes away the sludge and dirty fluid is

                  the preferred disposal method.  Steam cleaning and/or

                  pressure cleaning must be done in an area designed to collect

                  and contain the cleaning effluent.  The system may recycle,

                  collect or treat the effluent.

     

                  1.   If detergents or solvents are not used, an

                              oil/water separator connected to sanitary sewer

                              will usually allow effluent to meet sewer standards.

           

            2.   The collected washwater may be treated and

                              subsequently discharged to the sanitary sewer

                              system, if it meets sanitary sewer standards, or

                              recycled for further reuse.  For existing

                              facilities on septic tank, it can be hauled to a

                              sewage treatment plant by a permitted septic tank

                              hauler.  Industrial waste cannot be discharged to

                              septic tank.

     

                  3.   The effluent wastewater generated from washing the

                              inside of cement trucks may be discharged to a DERM

                              approved lined settling pond.  This effluent may not

                              contain engine washing effluent, solvents or other

                              hazardous materials.  Waste cement must not be

                              discharged to open ground.

     

         ***Plans for steamcleaning and/or pressure cleaning, and/or Recycling             Systems must be submitted to DERM for approval before construction. .                                           

6.    Special attention should be paid to storm drain (also known as

            storm sewer) locations.  Storm drains are designed to help

            alleviate rainwater build up.  These drains are not connected to

            the sanitary sewer system but rather assist in allowing rainwater

            to drain into the ground and groundwater.  Therefore, no

            discharges are to go to these storm drains.  Areas that are near

            storm drains must be kept free of oil, grease and other

            contaminants so that rainwater does not wash these materials into

            the storm drains.

         

7.   Used lead-acid batteries must be sent to a recycler.  Batteries

            must be stored on an impervious surface and under cover until

            shipment. 

 

8.   In all situations where the waste is deemed to be hazardous, a

            permitted hazardous waste transporter must be used to transport

            the waste to a federally approved hazardous waste disposal

            facility.  Hazardous waste manifests must be maintained at your

            facility.  The facility generating the hazardous waste is required

            to obtain an Environmental Protection Agency identification

            number, unless classified as a conditionally exempt generator by

            contacting:

Notification Coordinator

Bureau of Waste Planning and Regulation

Florida Department of Environmental Protection

Twin Towers Office Building Room 421

2600 Blair Stone Road

Tallahassee, Florida 32399-2400

(904) 488-4805   

 

9.   All hazardous waste must be disposed of via a permitted hazardous

            waste transporter and taken to a federally approved hazardous

            waste disposal facility.  Receipts of all waste disposals and

            hazardous waste manifests must be retained for no less than three   (3)

            years, at the generator facility and be available for review.

     

For facilities storing large amounts of chemicals and/or fuels:

        

10.  Storage

     

            a.   For facilities storing large amounts of chemicals and/or

                  fuels:

     

                  1.   All chemical and fuel storage must have secondary

                              containment.  This containment area should be able to

                              hold 110% of the volume of the largest single tank to be

                              stored in this area.

             

            2.   Chemical storage areas must be on an impervious surface

                              with secondary containment or a bermed and covered                      area away from drainage structures (e.g. floor drains or

                              storm drains).

     

11.  For facilities which generate dust;

        

      a.    The dust problem can be minimized by keeping the problem                areas wet down or damp.

         

All cement plants and rockmining facilities are required to have an

Annual Pollution Control Operating Permit.
