					 tanks must:
a. Have a liquid level
					 indicator.
b. Have an overflow and
					 a receiving basin or drain capable of receiving accidental spills or

					 BOD5 and suspended solids concentrations in accordance
					 with the issued discharge permit or certificate limitations.
B. General design. Conventional effluent
					 filtration shall be accomplished at a uniform rate of one to five gallons per
					 minute per square foot of surface area through filter media consisting of a
					 specified depth of the following materials, either as a single media, or as an
					 approved combination of multiple layers:

					 shall not exceed 90% of the filter media depth.
c. Each filter shall have a means of
					 individually controlling the filtration rate.
2. The effluent filter walls shall not
					 protrude into the filter media and the incoming flow shall be uniformly applied
					 to flooded media, in such a manner as to prevent media displacement. The height
					 of the filter walls must provide for adequate freeboard above the media surface
					 to prevent overflows.
3. The filter
					 shall be covered by a superstructure if determined necessary under local
					 climatic conditions. There shall be head room or adequate access to permit
					 visual inspection of the operation as necessary for maintenance.

Current through Register Vol. 40, No. 24, July 15, 2024
A conventional land treatment system utilizes a secondary
						process for pretreatment of sewage followed by irrigation, overland flow, or
						infiltration-percolation (or combination thereof) methods for applying the
						treated effluent to an approved site. Other natural treatment alternatives such
						as aquatic ponds and constructed wetlands may provide conventional sewage
						treatment. Reuse of treated effluents that meet the quality standards
						established by the DEQ for the reclamation and reuse of wastewater will be
						governed by DEQ permitting programs. However, the sewage treatment process that
						produces the reclaimed water will remain subject to evaluation by the
						department as prescribed by this chapter.

					 obtained at design loadings.
The following nutrient control processes will be
						considered:
1. Natural Systems-Aquatic
					 plant removal (APU) and proper plant management.
2. Suspended growth systems with adequate

Current through Register Vol. 40, No. 24, July 15, 2024
Ion exchange may be utilized as a unit operation in which
						ions are exchanged between two different materials, usually a solid-liquid, but
						may involve a liquid-liquid exchange. In wastewaters, the exchange usually
						involves a solid resin material consisting of readily ionized compounds.
						Treated effluent (secondary or advanced treatment) passes at a controlled rate
						through a certain volume of resin within a contactor. The removal of 90-95% of
						the ammonia nitrogen can be achieved by such treatment. Ion exchange may also
						be utilized for removing heavy metals, nitrates, phosphates, sulfides, phenol,
						and chlorophenols from wastewaters.
1.
					 The process specifically designed for ammonia nitrogen removal uses a
					 clinoptilolite resin. Many of the design considerations are applicable to other
					 types of ion exchange treatment, including:
a.
					 Flow, total dissolved solids, suspended solids, ion specific concentrations,
					 alkalinity, pH, and resin structure.
b. The rate of exchange based upon
					 selectivity of the resin, the exchange capacity of the resin, waste strength,
					 and the effluent requirements.
c.
					 The exchange capacity and break through point.
d. Certain contaminants which create
					 treatment problems in the operation of ion exchange. Where these contaminants
					 exist, their removal shall be provided for if necessary through the methods of
					 pretreatment listed in Table 10.

Current through Register Vol. 40, No. 24, July 15, 2024
A.
					 Design. The oxygen supply requirements for diffused aeration systems serving
					 suspended growth biological reactors should be established from the Alpha
					 factor and the Beta factor (9VAC25-790-690 E
					 6).
B. Alpha factor. The alpha
					 factor was once considered to be related only to wastewater characteristics,
					 primarily surfactants. Additional investigations have shown that the alpha
					 factor varies with other process conditions including mixing intensity,
					 suspended solids concentration, and other factors, particularly the method of
					 aeration. The alpha factor is unique for a particular wastewater treatment
					 facility but is difficult to accurately determine; however, standards of
					 practice for measuring the alpha factor have been proposed.
Reported observations on the variations of the alpha
						factor with diffuser type are as follows:
Bubble Size
Range of Alpha
Fine
0.4 - 0.55
Medium
0.7 - 0.8
Coarse
0.8 - 0.9
Other studies have similarly indicated lower alpha
						factors for fine bubble diffusers in comparison to coarse bubble diffusers.
						Summaries of reported values for alpha factors for mechanical aerators indicate
						a general range of 0.8 to greater than 1.0 with some values as low as 0.6.
						Increasing mixing intensity tends to increase the alpha factor.
C. Beta factor. The beta factor
					 has been observed to vary over a moderate range, although the variations are
					 generally less than observed variations of the alpha factor. One method
					 proposed for estimating the beta factor uses the TDS concentration of the
					 wastewater and the Standard Methods chart for saturation dissolved oxygen
					 concentrations at various chloride levels in which
Beta Factor =
						CSTC/CST,
where
CSTC-saturation dissolved oxygen
						concentration at temperature, T and chloride concentration, C
(Substitute chloride conc. for TDS conc. when using
						chart)
and
CST = saturation dissolved oxygen
						concentration at temperature, T and chloride concentration of 0.
Values reported for the beta factor for domestic
						wastewater are generally about 0.95 but considerable deviations from this value
						have been observed for industrial wastewater.

The board is charged with the development of regulations
					 which establish criteria that will provide for the protection of water quality,
					 and that also will accommodate economic development. All counties, cities and
					 towns in Tidewater Virginia shall comply with this chapter. Other local

					 in accordance with § 62.1-44.15:75 of the Code of Virginia.

Current through Register Vol. 40, No. 24, July 15, 2024
A. The
				  purpose of this chapter is to protect and improve the water quality of the
				  Chesapeake Bay, its tributaries, and other state waters by minimizing the
				  effects of human activity upon these waters and implementing the Act, which
				  provides for the definition and protection of certain lands called Chesapeake
				  Bay Preservation Areas, which if improperly used or developed may result in
				  substantial damage to the water quality of the Chesapeake Bay and its
				  tributaries.
B. This chapter
				  establishes the criteria that counties, cities and towns (hereinafter "local
				  governments") shall use to determine the extent of the Chesapeake Bay
				  Preservation Areas within their jurisdictions. This chapter establishes
				  criteria for use by local governments in granting, denying or modifying
				  requests to rezone, subdivide, or to use and develop land in Chesapeake Bay
				  Preservation Areas. This chapter identifies the requirements for changes which
				  local governments shall incorporate into their comprehensive plans, zoning
				  ordinances and subdivision ordinances and employ to ensure that the use and
				  development of land in Chesapeake Bay Preservation Areas shall be accomplished
				  in a manner that protects the quality of state waters pursuant to §§
				  62.1-44.15:74 and 62.1-44.15:76 of the Act.
Statutory Authority: §§ 62.1-44.15:69 and
