clarification of any point of information provided in accordance with 
this Section. Such clarification shall be provided in the shortest 
possible time, but no more than 30 days following receipt of a request.

Section V. Hydrodynamic Yield Measurement Method

1. The hydrodynamic measurement zone for each explosive means a 
cylindrical region coaxial with the emplacement hole of that explosive. 
This region extends in the direction of the entrance to the emplacement 
hole from the midpoint of the canister containing that explosive to the 
point at which the axis of the emplacement hole intersects a spherical 
surface whose radius, measured from the midpoint of the canister 
containing the explosive, is equal in meters to 10 times the cube root 
of the planned yield in kilotons of that explosive, or 25 meters, 
whichever is greater. The length of this region in the opposite 
direction from the same midpoint of the canister is equal in meters to 
three times the cube root of the planned yield in kilotons of that 
explosive, or 7.5 meters, whichever is greater. The radius of this
region is equal in meters to three times the cube root of the planned 
yield in kilotons of that explosive, or 7.5 meters, whichever is 
greater.
2. For hydrodynamic yield measurement the following procedures shall
apply:
(a) Designated Personnel shall emplace, for each explosive, the 
equipment specified in paragraph 5(a) of Section VIII of this 
Protocol in the same emplacement hole as the explosive. The 
equipment specified in paragraphs 5(a) and 5(b) of Section VIII of 
this Protocol shall be installed, in accordance with installation 
instructions provided in accordance with paragraph 8(a)(i) of 
Section VIII of this Protocol, by Designated Personnel under 
observation of personnel of the Party carrying out the explosion 
and with their assistance, if Designated Personnel have requested 
such assistance. The location of each recording facility and the 
command and monitoring facility of the Verifying Party shall be
determined by agreement of the Parties with respect to each 
particular explosion. This equipment shall be operated by 
Designated Personnel;
(b) for each explosive, the equipment specified in paragraph 5(a) 
of Section VIII of this Protocol shall be installed so that the 
end point of the equipment farthest from the emplacement hole 
entrance is three meters from the surface of the explosive 
canister closest to the emplacement hole entrance as measured 
along the axis of the emplacement hole. The location of this 
equipment relative to the axis of the emplacement hole shall be 
agreed upon by the Parties. No more than six sensor channels shall 
be installed for each explosive. Each Party shall make documented 
records of measured distances to the sensors. These records shall 
be exchanged by the Parties; 
(c) explosive canisters with a length greater than 10 meters or a 
diameter greater than three meters shall be used only if prior 
agreement has been reached between the Parties establishing, in 
each specific case, provisions for their use; and 
(d) the Party carrying out the explosion shall fill all voids 
other than the explosive canister within the hydrodynamic 
measurement zone of each explosive in each emplacement hole with 
stemming material. This stemming material, beginning no more than 
three meters from each explosive canister cover towards the 
entrance of the hole, and proceeding in that direction, shall
have a bulk density no less than 70 percent of the average density 
of the surrounding rock. An alternate stemming material may be 
used for filling the remainder of the hydrodynamic measurement 
zone of that explosive. For any explosive emplaced in an 
emplacement hole whose diameter is less than 30 centimeters and 
emplaced at a distance of more than 1.5 kilometers from the 
entrance of the hole, an alternate stemming material may be used 
for filling the entire hydrodynamic measurement zone of that 
explosive. If more than one explosive is emplaced in a single 
emplacement hole, the Parties shall agree upon an alternate 
stemming material for filling the entire hydrodynamic measurement 
zone of each explosive other than the explosive nearest the 
entrance of the emplacement hole if the emplacement hole diameter 
is greater than 30 centimeters but less than 60 centimeters. Any 
alternate stemming material shall have a bulk density no less than 
1.2 grams per cubic centimeter. Pipes located within the 
hydrodynamic measurement zone need not be filled with stemming 
material if they have a cross-sectional area less than 10 square
centimeters, or if they have a cross-sectional area less than 100     
square centimeters and a length less than one meter.  Costs 
incurred by the party carrying out the explosion to ensure, within 
the hydrodynamic measurement zone, a density of stemming material 
no less than 70 percent of the average density of the surrounding 
rock shall be borne by the Verifying Party.
3. For a group explosion the Party carrying out the explosion shall 
ensure that the emplacement point of each explosive canister, the 
detonation sequence, and the time intervals between individual 
explosions are such that no explosion in the group shall interfere with 
the hydrodynamic yield measurement of an other individual explosion. 
With the exception of group explosions provided or in paragraph 2 of 
Section II of this Protocol, if the technological characteristics of the 
project of which the group explosion is a part make it impossible to 
satisfy this requirement, the Parties, prior to the beginning of 
emplacement of explosives, shall agree upon alternative hydrodynamic or 
other verification procedures. 
4. In preparation for the use  of the hydrodynamic yield measurement 
method, the Verifying Party shall have the right to confirm the validity
