(Truck trip ends are one-directional. For example, one (1) truck entering the mine = one (1) trip end; the same truck leaving the mine = a second trip end.) Applicants may enter into a developer's agreement to equitably share or recoup paving costs.
1.
Paved haul routes shall meet the following specifications:
a.
Minimum pavement width shall be twenty-four (24) feet, unless reduced by the Public Works Director for haul route segments not used by the general public.

The county's adopted level of service (LOS) for the project haul route and intersections significantly impacted by project truck traffic shall be evaluated using passenger car equivalents (PCEs) for anticipated haul truck traffic based on Institute of Transportation Engineers (ITE) standards for PCEs. (For example, a PCE of 2.3 passenger cars per haul truck would be used to evaluate the LOS for the project haul route and intersections impacted by the project.) Such evaluation shall use average daily haul truck traffic plus a fifteen (15) percent peaking factor. Where a haul route segment(s) is shared by more than one (1) mining operation, haul truck traffic from all the mining operations shall be used in the LOS evaluation.
(h)
To provide gaps in haul truck traffic on haul routes and prevent significant haul truck backups at haul route/major road intersections, the following truck frequency standards shall be satisfied:
1.
A mining operator shall limit the frequency of haul truck trips to and from his mining operation on two-lane roads to no more than one hundred twenty (120) trip ends per hour, with trips ends as defined in subsection (4)(f) above. This frequency standard may be exceeded for delivery of materials to special or large projects if the operator first obtains approval from the Public Works Director of a maintenance of traffic plan. Such plan shall include a coordinated hauling schedule if a shared haul route is used and method of maintaining acceptable traffic flow to provide "gaps" for nonproject traffic along the haul route. Said plan may also require additional improvements to or security for maintaining the haul route, and may require coordination with other mining operators.
2.
Along a two-lane haul route segment, cumulative haul truck trips shall not exceed two hundred forty (240) trip ends per hour, with trip ends as defined in subsection (4)(f) above.
3.
To aid the county in monitoring haul truck trip frequency, applicants shall provide haul truck log information to the Public Works Director or his designee, upon request.
(i)
Where one (1) or more haul route segments are shared by more than one (1) mining operation, the operators of the affected mines shall obtain public works approval of a haul route improvement and maintenance plan that addresses shared responsibilities and use of posted security in the event that one (1) or more parties fail to perform its fair-share maintenance.

Where a mining operation consists only of the removal of a mound and does not consist of lowering the elevation of ground below the neighboring property, an exception of the one hundred fifty (150) feet setback may be permitted at the time of site plan approval. In addition, the applicant shall satisfy the following:
1.
A three-hundred-foot setback from adjacent occupied structures (structures existing as of the date of site plan application for the mining project) to mining pits, on-site haul roads, and material stockpile areas.
(c)
All mining sites that exceed ten (10) acres in area shall be subject to the provisions of section 934.05, water management standards. Projects creating waterbodies must also provide a safety/security plan for the mining operation phase, including, but not limited to, fences and/or berms, access, control, and other security methods.
(d)
If the project site is of a size that falls below St. Johns River Water Management District permitting thresholds and is located (in whole or part) on the Atlantic coastal sand ridge, no excavation governed by a mining permit shall result in an average elevation of less than twenty-five (25) feet mean sea level (MSL) for that portion of the project site located on the sand ridge. Mining project sites that are large enough to fall within Saint Johns River Water Management District (SJRWMD) permitting requirements shall conform to SJRWMD permitting requirements concerning depth of mining and all other applicable SJRWMD permitting requirements.
(e)
If the project site is adjacent to a residential district or to an agriculturally-zoned parcel of ten (10) acres or less, the perimeter of the site adjacent to such an area shall include a fifty-foot wide bufferyard and a type "A" buffer or its equivalent along said site boundary.
(f)
No crusher, mixing plant, bin, tank, or structure directly involved in the production process shall be located less than:
1.
Six hundred (600) feet to any adjacent property zoned residential, or
2.
Six hundred (600) feet or twenty-five (25) percent of the project site width, whichever is less, to any adjacent property not zoned residential. In no case shall the setback to property not zoned residential be less than two hundred fifty (250) feet.
(g)
No explosives or active chemical agents shall be used to extract or process materials on site.
(h)
The community development department shall issue a mining permit upon site plan and administrative permit approval, and a determination that all site plan release and applicable Chapter 934 requirements are satisfied for permit issuance.
(i)
Nothing herein shall be construed as a requirement that an operator of an existing sand mine shall cease operations until a mining site plan has been approved, provided a mining site plan has been previously approved and maintained.
(j)
Specific mining activity timeframes, from the date of initial mining permit issuance, are established based upon the estimated quantity of material to be removed. Excavation, hauling, or other mining activities occurring beyond these timeframes (along with any approved extension requests), are prohibited unless extended by the board of county commissioners as provided below:
Note: Owners/operators of mining operations approved prior to adoption of the fifteen (15) year and twenty (20) year time frames cited above may obtain a staff level approval to modify their mining operation time frames consistent with the time frames cited above, if the mining operation is in compliance with its county site plan approval, mining permit, and all jurisdictional agency permits related to the mining operation.
1.
These timeframes may be extended by the board of county commissioners upon an applicant's request made prior to the normal timeframe expiration. The board may grant an extension if it determines that the mining operation has been inactive for a period of time due to market conditions such as an economic recession. The board shall not extend the initial timeframe by a period of time greater than the determined period of inactivity.
(k)
The mining site shall be restored in accordance with the approved restoration plan. Within five (5) months of the end of the approved timeframe (including any extension), the operator shall submit to the county a written notice stating that the mine is inactive and has been restored. Such notice shall be accompanied by two (2) signed and sealed as-built surveys of the site demonstrating substantial conformance with the approved project restoration plan. Restoration work shall then be inspected for compliance with the approved project restoration plan by county staff within six (6) months of the end of the approved timeframe (including any extension) for the mining operation. None of the security posted with the county in accordance with these mining regulations shall be returned unless and until the requirements of this subsection (k) are satisfied.
(4)
Operating conditions of mining.
(a)
Mining operations located west of I-95 and not adjacent to a residential district or an agriculturally-zoned parcel of ten (10) acres or less, shall not be limited to specific hours of operation unless a determination is made by the planning and zoning commission concerning the need to limit hours of operation due to the anticipated impact of the mining operation on surrounding properties. If a project site or any portion of a project's primary haul route is located east of I-95, or if any portion of a project site is located adjacent to a residential zoning district or agriculturally-zoned parcel of ten (10) acres or less, then the mine shall be limited to operation between the hours of 7:00 a.m. to 6:00 p.m. on weekdays; hauling off-site shall not occur after 5:00 p.m. on any day. Operation other than 7:00 a.m. to 6:00 p.m. may be permitted by the board of county commissioners if the board determines that the impact of the mining operation on surrounding properties will not constitute a nuisance to the neighborhood, contrary to county noise and vibration control regulations.
(b)
The land surface shall be restored to a condition which is in complete compliance with the site plan for reclamation and rehabilitation of the area. The mining excavation pit shall not be located within one hundred fifty (150) feet of the projected right-of-way line of any existing or proposed public road nor within one hundred fifty (150) feet of the outer perimeter of the land area. Where a mining operation consists only of the removal of a mound and does not consist of lowering the elevation of ground below the neighboring property, an exception to the one-hundred-fifty-foot outer perimeter setback may be permitted at the time of the site plan approval. All slopes and banks shall be sloped at a ratio of not steeper than three (3) feet horizontal to one (1) foot vertical, graded, grassed and stabilized.
(c)
Permanent project site boundary corners and the one-hundred-fifty-foot project perimeter setback line shall be marked with intermediate stakes at a minimum interval of three hundred (300) feet, and maintained with visible flags in the field, in accordance with the approved project site plan.
(d)
Between August 1 and October 1 of each year, the operator holding a valid mining permit shall submit to the community development department the following:
• A written request to renew the annual mining permit,
• A written statement identifying the current operator and engineer of record,
• A calculation of the land area mined and reclaimed during the preceding year,
• A calculation of the land area expected to be mined,
• A calculation of the land area planned for reclamation during the coming year,
• Verification that all county and jurisdictional agency permits are valid and that the operation is in compliance with all conditions of site plan approval,
• The expiration dates for all jurisdictional agency permits
• A copy of all monitoring reports and monitoring data provided to jurisdictional agencies during the preceding year.
• A summary indicating the status of compliance with monitored thresholds and any instances of noncompliance during the preceding year, and
• An updated, dimensional site sketch of current conditions.
1.
No annual mining permit shall be renewed unless and unless the mining site is deemed to be in compliance with the approved project site plan. Failure to file the required annual progress report by October 1, or obtain renewal of the permit by November 1, shall be grounds for suspension of the mining operation; however, an extension of time for filing or obtaining the permit renewal may be granted by the community development director or his designee upon request and for reasonable cause.
(5)
Posted security.
(a)
Intent. Compliance and restoration security shall be posted to ensure that the site is developed, operated, and restored in conformance with the approved mining site plan and restoration plan. The compliance security may be forfeited as a penalty for violations as provided in section 934.08. The restoration security is to provide funds to guarantee that the site is restored in compliance with the approved restoration plan and may be forfeited as provided in section 934.09.
(b)
Amount. The compliance security shall be posted in the amount of one thousand dollars ($1,000.00) per acre of the project site area upon which mining activities are conducted and authorized via the mining permit. For purposes of the compliance security calculation, such areas shall include any cleared or stabilized area used or permitted to be used for access, staging, hauling, excavation, stockpiling, recharging, processing, parking, or storage. The minimum amount of the compliance security shall be ten thousand dollars ($10,000.00). The restoration security shall be posted in an amount equal to one hundred twenty-five (125) percent of the project engineer's itemized cost estimate to restore the site, approved by the Public Works Director or his designee. Said estimate shall be based on the cost to restore the mining activity site area in accordance with the approved restoration plan. The cost estimate and resulting required security amount shall be updated and revised every three (3) years during the life of the mining operation. The cost estimate must be approved by the Public Works Director or his designee. The minimum amount of the restoration security shall be ten thousand dollars ($10,000.00).
(c)
Form. The security shall be provided in a form consistent with the county's standards for subdivision improvements maintenance security as provided in [subsection] 913.10(2).
(d)
Phasing. When one (1) phase of twenty (20) acres or less is completed and in conformance with the approved site plan, the compliance security may be transferred to the next phase under the approved site plan. No more than two (2) phases may be mined concurrently; however, each phase shall be fully covered by posted security, as required by this chapter. Restoration security may be transferred to the next phase when restoration of the previous phase has been completed in accordance with the approved restoration plan.
(e)
Renewal. Within thirty (30) days preceding security expiration, a mining operator shall renew the posted security or provide new security, in a form and amount approved by the community development director and county attorney. In the event that timely security renewal does not occur, the county is authorized to have the security forfeited. This process shall be continued through the completion of the mining operation.
(Ord. No. 90-16, § 1, 9-11-90; Ord. No. 95-10, § 21, 5-31-95; Ord. No. 96-6, § 21, 2-27-96; Ord. No. 2007-035, § 1, 10-23-07; Ord. No. 2008-023, § 5, 12-19-08; Ord. No. 2018-024, § 2, 11-20-18)
Any mining permit issued pursuant to this chapter shall be subject to the following provisions:
(1)
The applicant shall ensure that neither public nor private property will be damaged by the hauling of mined materials and that hazardous traffic conditions will not be created. All such applications shall identify an authorized fill hauling route. If private roads or easements are intended to be used, written permission shall be submitted from the person or persons owning said road or easement as part of the application materials. Load limits shall not be exceeded along the haul route;
(2)
Where deemed necessary by the county engineer, mats, culvert, ramps, or paved drives shall be placed at entrances and/or exists of haul sites in such positions that pavement edges, shoulders, curbs and sidewalks will be protected from damage;
(3)
If any of the hauling route is over county maintained, unpaved roads, the permittee must maintain that section of the hauling route during the hauling operation, and security for this purpose may be required, as determined by the county engineer. If security is required based upon number of trips on unpaved roads, the frequency of the trips, and the duration of the activity, said security shall be a minimum of five thousand dollars ($5,000.00) and shall not exceed ten thousand dollars ($10,000.00) per mile of unpaved roadway identified on the approved hauling route for the mine;
(a)
The Public Works Director or his designee is authorized to perform road maintenance on behalf of the mining owner/operator and have the road maintenance security forfeited if the mining owner/operator has failed to perform required road maintenance within three (3) working days of written notice. Forfeited security shall be used to fund the cost of road maintenance work performed. Upon forfeiture, mining operation hauling shall cease and shall not recommence until adequate road maintenance is performed and new road maintenance security is submitted. The unexpended balance of the security shall be returned to the mining owner/operator or applied to the newly posted security.
(4)
Where vehicles hauling excavated materials use public roads, such vehicles shall be covered in a manner to prevent fill spillage, to the satisfaction of the county engineer;
(5)
All hauling vehicles shall have the trucking company name (or truck owner's name if vehicle is privately owned) prominently displayed on the sides of the vehicle.
(Ord. No. 90-16, § 1, 9-11-90; Ord. No. 2007-035, § 1, 10-23-07; Ord. No. 2008-023, § 6, 12-19-08)
(1)
Enforcement and penalties for violations.
(a)
Generally. The county may impose but is not limited to the following types of penalties for violations of the approved project site plan, mining permit, and any conditions attached thereto:
• Stop work for all or a portion of the mining operation;
• Forfeiture of posted security;
• Termination of mining permit;
Penalties imposed shall be based upon the following:
• Timelines and adequacy of operator/owner response to take corrective action. Harsher penalties shall be imposed for low and/or inadequate operator/owner responses.
• Severity and degree of violation(s). Harsher penalties shall be imposed for violations that have broader and/or longer lasting negative impacts.
• Number of violations. Harsher penalties shall be imposed if numerous violations have occurred.
(b)
Violation and compliance process. Upon observing a potential violation, county staff shall contact the mining operator or owner, advise him/her of the potential violation and corrective action, and document the observation and contact with the operator or owner. If the operator or owner takes immediate and appropriate corrective action and county staff confirms compliance, then no further county compliance/enforcement action is needed. If, however, the operator or owner fails to take immediate and appropriate corrective action, then county staff shall issue a formal letter of violation, citing the violation along with evidence of the violation, prescribing corrective action, and providing a compliance date. If the operator or owner corrects the violation on or before the compliance date, then the violation shall be considered a "Formal Resolved Violation". If, however, the operator or owner fails to correct the violation on or before the compliance date, then the violation shall be considered a "Formal Unresolved Violation".
(c)
Progressive penalty process.
1.
If an operator or owner has a formal unresolved violation or five (5) or more Formal Resolved Violations within a one-year period, then county staff shall schedule a penalty determination hearing before the board of county commissioners. At least ten (10) days prior to the hearing, county staff shall provide written notice of the hearing to the mining operator, mine owner, and owners of immediately adjacent properties. At the hearing, county staff shall present evidence of the violation(s) along with an evaluation of the operator's or owner's responsiveness to take corrective action(s), the severity and degree of the violation(s), and the number of violations. The owner or operator shall be given an opportunity to rebut staff's evidence/evaluation and provide his own evidence/evaluation.
2.
Upon hearing the evidence, the Board of County Commissioners shall determine whether or not a penalty shall be imposed. For any given mining project, the Board of County Commissioners is authorized to impose forfeiture of the project's compliance security in an amount not to exceed twenty-five thousand dollars ($25,000.00) as a penalty.
3.
If, during the life of the project, a penalty determination hearing is held after the Board of County Commissioners has imposed a penalty against the project at a previous penalty determination hearing, then at the "second" hearing the Board of County Commissioners is authorized to impose forfeiture of the entire compliance security with no limit on the amount forfeited as a penalty.
4.
If, during the life of the project, a penalty determination hearing is held after the Board of County Commissioners has imposed a penalty against the project at each of two (2) previous penalty determination hearings, then at the "third" hearing the Board of County Commissioners is authorized to terminate the project mining permit, impose forfeiture of compliance security, and impose forfeiture of road maintenance and/or restoration security to cover costs of required maintenance or restoration.
5.
At any penalty determination hearing, the Board of County Commissioners is authorized to impose forfeiture of any project security posted for road maintenance to pay for road maintenance costs incurred by the county due to failure of the operator or owner to properly maintain the haul route.
(d)
Traffic law enforcement. If county staff finds reason to believe that haul truck drivers are violating traffic laws on the project haul route (e.g. speeding), then staff will contact the sheriff's office to request traffic law enforcement along the project haul route. Any traffic citation for a moving violation given to a haul truck driver on a project haul route shall constitute a Formal Resolved Violation against the project served by that haul truck driver. Notice of such Formal Resolved Violation shall be provided to the project operator and owner.
In the event that, at a penalty determination hearing, the Board of County Commissioners finds traffic law violations (moving violations) by haul truck drivers serving the project site, the Board of County Commissioners is authorized to assess the operator or owner the cost to the county to hire contract traffic law enforcement personnel to conduct special traffic law enforcement activities along the project haul route. That assessment shall be in addition to other penalties that it may impose.
(Ord. No. 2008-023, § 7, 12-19-08)
(1)
All permits shall expire one year from the date of issuance, except when otherwise authorized by a site plan or subdivision approval. A permit may be renewed by paying a renewal fee and filing an annual progress report demonstrating that the permit criteria have been met. The report must meet the specification of section 934.07(4)(d) of this chapter.
(2)
For all permitted projects, a record drawing by a surveyor or engineer registered in the State of Florida shall be provided to the community development department at the completion of the permitted project. The record drawing shall contain sufficient information to indicate that all of the requirements of this chapter have been satisfied, and shall include cross-sections of the excavation and a plan drawing which locates the extent of the excavation with dimensions to all property lines.
(3)
The permittee shall maintain a copy of the mining permit, approved site plan, approved stormwater management permit plans, and a copy of all jurisdictional agency permits on the permitted site during the entire permit period. Said permit shall be fully visible at a location accessible to county inspectors that is noted in the mining permit.
(4)
No permit shall be issued under this chapter if a violation of this chapter is existing on the subject property, nor shall any permits be issued to any person who is currently in violation of this chapter. This section is not intended to prohibit the issuance of a permit to correct any existing violation.
(Ord. No. 90-16, § 1, 9-11-90; Ord. No. 2008-023, § 8, 12-19-08)
The county recognizes that approved and permitted mining operations in existence prior to December 19, 2008, may continue as approved and permitted. Such mining operations, however, shall be subject to the following requirements of these mining regulations adopted December 9, 2008:

(Truck trip ends are one-directional. For example, one (1) truck entering the mine = one (1) trip end; the same truck leaving the mine = a second trip end.) Applicants may enter into a developer's agreement to equitably share or recoup paving costs.
1.
Paved haul routes shall meet the following specifications:
a.
Minimum pavement width shall be twenty-four (24) feet, unless reduced by the Public Works Director for haul route segments not used by the general public.
b.
Pavement thickness base and sub-base depths shall meet county thoroughfare and truck route specifications, including ESAL (equivalent single axle loads) and pavement strength coefficients.
(g)
The county's adopted level of service (LOS) for the project haul route and intersections significantly impacted by project truck traffic shall be evaluated using passenger car equivalents (PCEs) for anticipated haul truck traffic based on Institute of Transportation Engineers (ITE) standards for PCEs. (For example, a PCE of 2.3 passenger cars per haul truck would be used to evaluate the LOS for the project haul route and intersections impacted by the project.) Such evaluation shall use average daily haul truck traffic plus a fifteen (15) percent peaking factor. Where a haul route segment(s) is shared by more than one (1) mining operation, haul truck traffic from all the mining operations shall be used in the LOS evaluation.
(h)
To provide gaps in haul truck traffic on haul routes and prevent significant haul truck backups at haul route/major road intersections, the following truck frequency standards shall be satisfied:
1.
A mining operator shall limit the frequency of haul truck trips to and from his mining operation on two-lane roads to no more than one hundred twenty (120) trip ends per hour, with trips ends as defined in subsection (4)(f) above. This frequency standard may be exceeded for delivery of materials to special or large projects if the operator first obtains approval from the Public Works Director of a maintenance of traffic plan. Such plan shall include a coordinated hauling schedule if a shared haul route is used and method of maintaining acceptable traffic flow to provide "gaps" for nonproject traffic along the haul route. Said plan may also require additional improvements to or security for maintaining the haul route, and may require coordination with other mining operators.
2.
Along a two-lane haul route segment, cumulative haul truck trips shall not exceed two hundred forty (240) trip ends per hour, with trip ends as defined in subsection (4)(f) above.
3.
To aid the county in monitoring haul truck trip frequency, applicants shall provide haul truck log information to the Public Works Director or his designee, upon request.
(i)
Where one (1) or more haul route segments are shared by more than one (1) mining operation, the operators of the affected mines shall obtain public works approval of a haul route improvement and maintenance plan that addresses shared responsibilities and use of posted security in the event that one (1) or more parties fail to perform its fair-share maintenance.

1.
Six hundred (600) feet to any adjacent property zoned residential, or
2.
Six hundred (600) feet or twenty-five (25) percent of the project site width, whichever is less, to any adjacent property not zoned residential. In no case shall the setback to property not zoned residential be less than two hundred fifty (250) feet.
(g)
No explosives or active chemical agents shall be used to extract or process materials on site.
(h)
The community development department shall issue a mining permit upon site plan and administrative permit approval, and a determination that all site plan release and applicable Chapter 934 requirements are satisfied for permit issuance.
(i)
Nothing herein shall be construed as a requirement that an operator of an existing sand mine shall cease operations until a mining site plan has been approved, provided a mining site plan has been previously approved and maintained.
(j)
Specific mining activity timeframes, from the date of initial mining permit issuance, are established based upon the estimated quantity of material to be removed. Excavation, hauling, or other mining activities occurring beyond these timeframes (along with any approved extension requests), are prohibited unless extended by the board of county commissioners as provided below:
Note: Owners/operators of mining operations approved prior to adoption of the fifteen (15) year and twenty (20) year time frames cited above may obtain a staff level approval to modify their mining operation time frames consistent with the time frames cited above, if the mining operation is in compliance with its county site plan approval, mining permit, and all jurisdictional agency permits related to the mining operation.
1.
These timeframes may be extended by the board of county commissioners upon an applicant's request made prior to the normal timeframe expiration. The board may grant an extension if it determines that the mining operation has been inactive for a period of time due to market conditions such as an economic recession. The board shall not extend the initial timeframe by a period of time greater than the determined period of inactivity.
(k)
The mining site shall be restored in accordance with the approved restoration plan. Within five (5) months of the end of the approved timeframe (including any extension), the operator shall submit to the county a written notice stating that the mine is inactive and has been restored. Such notice shall be accompanied by two (2) signed and sealed as-built surveys of the site demonstrating substantial conformance with the approved project restoration plan. Restoration work shall then be inspected for compliance with the approved project restoration plan by county staff within six (6) months of the end of the approved timeframe (including any extension) for the mining operation. None of the security posted with the county in accordance with these mining regulations shall be returned unless and until the requirements of this subsection (k) are satisfied.
(4)
Operating conditions of mining.
(a)
Mining operations located west of I-95 and not adjacent to a residential district or an agriculturally-zoned parcel of ten (10) acres or less, shall not be limited to specific hours of operation unless a determination is made by the planning and zoning commission concerning the need to limit hours of operation due to the anticipated impact of the mining operation on surrounding properties. If a project site or any portion of a project's primary haul route is located east of I-95, or if any portion of a project site is located adjacent to a residential zoning district or agriculturally-zoned parcel of ten (10) acres or less, then the mine shall be limited to operation between the hours of 7:00 a.m. to 6:00 p.m. on weekdays; hauling off-site shall not occur after 5:00 p.m. on any day. Operation other than 7:00 a.m. to 6:00 p.m. may be permitted by the board of county commissioners if the board determines that the impact of the mining operation on surrounding properties will not constitute a nuisance to the neighborhood, contrary to county noise and vibration control regulations.
(b)
The land surface shall be restored to a condition which is in complete compliance with the site plan for reclamation and rehabilitation of the area. The mining excavation pit shall not be located within one hundred fifty (150) feet of the projected right-of-way line of any existing or proposed public road nor within one hundred fifty (150) feet of the outer perimeter of the land area. Where a mining operation consists only of the removal of a mound and does not consist of lowering the elevation of ground below the neighboring property, an exception to the one-hundred-fifty-foot outer perimeter setback may be permitted at the time of the site plan approval. All slopes and banks shall be sloped at a ratio of not steeper than three (3) feet horizontal to one (1) foot vertical, graded, grassed and stabilized.
(c)
Permanent project site boundary corners and the one-hundred-fifty-foot project perimeter setback line shall be marked with intermediate stakes at a minimum interval of three hundred (300) feet, and maintained with visible flags in the field, in accordance with the approved project site plan.

Load limits shall not be exceeded along the haul route;
(2)
Where deemed necessary by the county engineer, mats, culvert, ramps, or paved drives shall be placed at entrances and/or exists of haul sites in such positions that pavement edges, shoulders, curbs and sidewalks will be protected from damage;
(3)
If any of the hauling route is over county maintained, unpaved roads, the permittee must maintain that section of the hauling route during the hauling operation, and security for this purpose may be required, as determined by the county engineer. If security is required based upon number of trips on unpaved roads, the frequency of the trips, and the duration of the activity, said security shall be a minimum of five thousand dollars ($5,000.00) and shall not exceed ten thousand dollars ($10,000.00) per mile of unpaved roadway identified on the approved hauling route for the mine;
(a)
The Public Works Director or his designee is authorized to perform road maintenance on behalf of the mining owner/operator and have the road maintenance security forfeited if the mining owner/operator has failed to perform required road maintenance within three (3) working days of written notice. Forfeited security shall be used to fund the cost of road maintenance work performed. Upon forfeiture, mining operation hauling shall cease and shall not recommence until adequate road maintenance is performed and new road maintenance security is submitted. The unexpended balance of the security shall be returned to the mining owner/operator or applied to the newly posted security.
(4)
Where vehicles hauling excavated materials use public roads, such vehicles shall be covered in a manner to prevent fill spillage, to the satisfaction of the county engineer;
(5)
All hauling vehicles shall have the trucking company name (or truck owner's name if vehicle is privately owned) prominently displayed on the sides of the vehicle.
(Ord. No. 90-16, § 1, 9-11-90; Ord. No. 2007-035, § 1, 10-23-07; Ord. No. 2008-023, § 6, 12-19-08)
(1)
Enforcement and penalties for violations.
(a)
Generally. The county may impose but is not limited to the following types of penalties for violations of the approved project site plan, mining permit, and any conditions attached thereto:
• Stop work for all or a portion of the mining operation;
• Forfeiture of posted security;
• Termination of mining permit;
Penalties imposed shall be based upon the following:
• Timelines and adequacy of operator/owner response to take corrective action. Harsher penalties shall be imposed for low and/or inadequate operator/owner responses.
• Severity and degree of violation(s). Harsher penalties shall be imposed for violations that have broader and/or longer lasting negative impacts.
• Number of violations. Harsher penalties shall be imposed if numerous violations have occurred.
(b)
Violation and compliance process. Upon observing a potential violation, county staff shall contact the mining operator or owner, advise him/her of the potential violation and corrective action, and document the observation and contact with the operator or owner. If the operator or owner takes immediate and appropriate corrective action and county staff confirms compliance, then no further county compliance/enforcement action is needed. If, however, the operator or owner fails to take immediate and appropriate corrective action, then county staff shall issue a formal letter of violation, citing the violation along with evidence of the violation, prescribing corrective action, and providing a compliance date. If the operator or owner corrects the violation on or before the compliance date, then the violation shall be considered a "Formal Resolved Violation". If, however, the operator or owner fails to correct the violation on or before the compliance date, then the violation shall be considered a "Formal Unresolved Violation".
(c)
Progressive penalty process.
1.
If an operator or owner has a formal unresolved violation or five (5) or more Formal Resolved Violations within a one-year period, then county staff shall schedule a penalty determination hearing before the board of county commissioners. At least ten (10) days prior to the hearing, county staff shall provide written notice of the hearing to the mining operator, mine owner, and owners of immediately adjacent properties. At the hearing, county staff shall present evidence of the violation(s) along with an evaluation of the operator's or owner's responsiveness to take corrective action(s), the severity and degree of the violation(s), and the number of violations. The owner or operator shall be given an opportunity to rebut staff's evidence/evaluation and provide his own evidence/evaluation.
2.
Upon hearing the evidence, the Board of County Commissioners shall determine whether or not a penalty shall be imposed. For any given mining project, the Board of County Commissioners is authorized to impose forfeiture of the project's compliance security in an amount not to exceed twenty-five thousand dollars ($25,000.00) as a penalty.
3.
If, during the life of the project, a penalty determination hearing is held after the Board of County Commissioners has imposed a penalty against the project at a previous penalty determination hearing, then at the "second" hearing the Board of County Commissioners is authorized to impose forfeiture of the entire compliance security with no limit on the amount forfeited as a penalty.
4.
If, during the life of the project, a penalty determination hearing is held after the Board of County Commissioners has imposed a penalty against the project at each of two (2) previous penalty determination hearings, then at the "third" hearing the Board of County Commissioners is authorized to terminate the project mining permit, impose forfeiture of compliance security, and impose forfeiture of road maintenance and/or restoration security to cover costs of required maintenance or restoration.
5.
At any penalty determination hearing, the Board of County Commissioners is authorized to impose forfeiture of any project security posted for road maintenance to pay for road maintenance costs incurred by the county due to failure of the operator or owner to properly maintain the haul route.
(d)
Traffic law enforcement. If county staff finds reason to believe that haul truck drivers are violating traffic laws on the project haul route (e.g. speeding), then staff will contact the sheriff's office to request traffic law enforcement along the project haul route. Any traffic citation for a moving violation given to a haul truck driver on a project haul route shall constitute a Formal Resolved Violation against the project served by that haul truck driver. Notice of such Formal Resolved Violation shall be provided to the project operator and owner.
In the event that, at a penalty determination hearing, the Board of County Commissioners finds traffic law violations (moving violations) by haul truck drivers serving the project site, the Board of County Commissioners is authorized to assess the operator or owner the cost to the county to hire contract traffic law enforcement personnel to conduct special traffic law enforcement activities along the project haul route. That assessment shall be in addition to other penalties that it may impose.
(Ord. No. 2008-023, § 7, 12-19-08)
(1)
All permits shall expire one year from the date of issuance, except when otherwise authorized by a site plan or subdivision approval. A permit may be renewed by paying a renewal fee and filing an annual progress report demonstrating that the permit criteria have been met. The report must meet the specification of section 934.07(4)(d) of this chapter.
(2)
For all permitted projects, a record drawing by a surveyor or engineer registered in the State of Florida shall be provided to the community development department at the completion of the permitted project. The record drawing shall contain sufficient information to indicate that all of the requirements of this chapter have been satisfied, and shall include cross-sections of the excavation and a plan drawing which locates the extent of the excavation with dimensions to all property lines.
(3)
The permittee shall maintain a copy of the mining permit, approved site plan, approved stormwater management permit plans, and a copy of all jurisdictional agency permits on the permitted site during the entire permit period. Said permit shall be fully visible at a location accessible to county inspectors that is noted in the mining permit.
(4)
No permit shall be issued under this chapter if a violation of this chapter is existing on the subject property, nor shall any permits be issued to any person who is currently in violation of this chapter. This section is not intended to prohibit the issuance of a permit to correct any existing violation.
