EXHIBIT A.

Specific MSWLF pre­flight procedures and specific UAS preflight

procedures.

1) Landfill operators or MSWLF agent / s will be notified of UAS

operations. And will have the authority to cancel UAS operation at any

time. Written permission will be obtained before any preflight

procedures are initiated.

2) Entrances to landfills will be clearly marked that a UAS operation

will be in effect. The clearly marked identifiers will specify that

non­authorized individuals must remain 500 ft from the UAS operation.

Authorized individuals will sign a consent to enter the UAS operational

theater.

3) Individuals working within the area of UAS operation will be notified

that a UAS operation will be in effect.

4) The area of UAS inspection will be observed for obstacles that may

interfere with safe operation. If obstacles exist that would affect UAS

operations the UAS operation will cease.

5) The PIC and VO will be clearly identified. A 10 ft radius around the

PIC will be free of any individuals. If the 10ft radius is penetrated the

UAS operation will cease.

6) Local weather conditions will be monitored. UAS operations will not

be performed if wind speeds are at or greater than 10 MPH. UAS

operations will not be performed if air temperature is less than or

equal to 5 degrees/c or greater than or equal +50 degrees/c. UAS

operations will not be performed during occurrences of snow, rain,

ground fog or any weather related conditions that would affect "line of

sight" flights.

6) On site, the UAS will be connected to a laptop computer via USB

cable. Dji assistant software will be uploaded. The Dji assistant

software will be the most current version.
7) Via the DJI assistant software the PIC (pilot in charge) will verify

that the UAS has the most recent firmware installed. If the latest

firmware is not installed into the UAS the UAS operation will cease

until the latest firmware can be uploaded into the UAS.

8) While the UAS is connected to the DJI assistant software the

following functions will be performed.

A) The IMU ( internal measurement unit) will be assessed. If the IMU

fails to provide values within the manufacturer specifications the IMU

will undergo an advanced IMU calibration. The IMU status check

includes gyroscope X, Y, X values : Acceleration X, Y, X values :

Compass X, Y, Z values. If the IMU calibration fails to comply with the

manufacturer (DJI) specifications the UAS operation will be

suspended until the IMU values correspond with the manufacturers

specifications.

B) The transmitter controls will be calibrated via the DJI assistant

software. If the command stick calibration fails the UAS operation will

be suspended until the transmitter control values correspond with the

manufacturer specifications.

C) Flight values will be verified. Flight values include maximum

altitude in feet and maximum radius from home point in feet. Enabling

these safeguards within the DJI assistant software ensures that the

UAS cannot fly past the maximum set altitude or beyond the maximum

radius from the home point position.

D) The UAS multirotor battery will be assessed via DJI assistant

software. Battery will be observed for percentage of charge and

percentage of life. If the UASs' battery displays a charge or life at 90

percent or less the multirotor battery will not be used in the UAS

operation. Only UAS multirotor batteries that display a functional

charge and percentage of life at or greater than 90 percent will be

used in UAS operations.

9) The UAS will be disconnected from the laptop.
10) The UAS will be observed for structural defects that may affect

safe flight. If structural defects are observed that the PIC determines

could affect safe flight then the UAS operation will cease.

11) The UAS propellers will be observed for structural defects that

may affect safe flight. If structural defects are observed that the PIC

determines could affect safe flight then the UAS operation will cease.

12) 4 nine inch propellers will be placed on the DJI Phantom 2 Vision.

Propellers will be properly placed according to each motors' clockwise

and counter clockwise orientation. Only DJI self tightening propellers

will be used.

13) The DJI Phantom 2 Vision Intelligent Flight Battery will be visibly

inspected for defects. If the PIC determines that the flight battery has

defects that may affect safe flight then the UAS operation will cease.

14) The DJI Phantom 2 Vision Intelligent Flight Battery will be securely

installed into the DJI Phantom 2 Vision.

15) The UAS will be placed on a level nonferrous platform.

16) The UAS battery will be turned on. A second battery check will be

verified by the PIC. The PIC will verify battery charge by observing the

4 indicator lights on the outside of the battery. 4 green indicator lights

signals that the flight battery is fully charged.

17) The UAS transmitter will be installed with 4 fully charged AA

batteries. The UAS transmitter will then be turned on.

18) The WiFi extender will be turned on and verified that it is fully

charged. A fully charged WiFi extender can be verified by the green

indicator light.

A) The WiFi extender in, conjunction with an IPAD or Android

smartphone, enables the PIC to observe critical real time flight data of

the UAS. Critical flight data includes UA orientation, number of
satellite connections, battery life, altitude, speed, and distance from

home point.

B) The WiFi extender and IPAD does not replace line of site UAS

operation. UAS operations will be conducted with the PIC in command

of the UAS at all time. The UA aircraft will remain within site of the

PIC.

19) The UAS will have a compass calibration. The following is the

procedural sequence used to ensure proper compass calibration and

the observable indicators that the PIC will use to ensure that an

accurate compass calibration has been performed.

A) Verification that the UAS in turned on. UAS includes the Aircraft,

transmitter, WiFi extender. Additionally, the IPAD or Android device

will be turned on and the manufacturers' ground station software will

be displayed.

B) The S1 and S2 toggle switches will clearly be marked on the

transmitter. The S1 and S2 toggle switches on the transmitter will be

in the position 1

C) The S1 toggle switch on the transmitter will be rapidly flipped

from the position 1 to the position 3 for a minimum of 10 cycles. The

ending position of the S1 toggle switch will be in the position 1.

D) The UAS aircraft will display steady yellow LED lights along its 2

aft rotor arms indicating the UAS aircraft is ready for compass

calibration.

E) The UAS aircraft will be lifted to chest level of the PIC and

horizontally rotate 360 degrees. Steady green LED lights along the

aircrafts' to aft rotor arms will indicate that the UAS aircraft has

successfully completed the horizontal compass calibration.

F) From the horizontal position the UAS aircraft will be turned on its

vertical axis with nose facing downward. The UAS aircraft will be

rotated 360 degrees on its vertical axis.
G) The UAS aircraft will be placed on a nonferrous level surface.

Once the LED lights on the 2 aft rotor arms indicate steady green

blinking lights the UAS aircraft compass has been successfully

calibrated.

20) The UAS GPS connection will be assessed via the ground station.

A GPS connection equal to or greater than 7 satellite connections will

be verified. If less than 7 GPS satellite connections are connected

then the UAS operation will cease.

21) The UAS aircraft will be started via the radio transmitter and will

remain idle for no less than 1 minute. During the idle period the PIC

will observe the UAS aircraft for any abnormalities that may affect safe

flight. If abnormalities are observed the UAS operation will cease.

22) The PIC will make a final visual inspection of the flight area. The

final visual inspection will also verify that the UA has an unobstructed

path to the set home point in case GPS signal is lost and failsafe

procedures are initiated. UAS operation will cease if the PIC

determines that the UAS operation is deemed unsafe.
